This callback is called only from writepage_delalloc which in turn is guaranteed to be called from the data page writeout path. In the end there is no reason to have the call to this function to be indrected via the extent_io_ops structure. This patch removes the callback definition, exports the function and calls it directly. No functional changes. Reviewed-by:

Qu Wenruo authored
Enhance btrfs_verify_dev_extents() to remember previous checked dev extents, so it can verify no dev extents can overlap. Analysis from Hans: "Imagine allocating a DATA|DUP chunk. In the chunk allocator, we first set... max_stripe_size = SZ_1G; max_chunk_size = BTRFS_MAX_DATA_CHUNK_SIZE ... which is 10GiB. Then... /* we don't want a chunk larger than 10% of writeable space */ max_chunk_size = min(div_factor(fs_devices->total_rw_bytes, 1), max_chunk_size); Imagine we only have one 7880MiB block device in this filesystem. Now max_chunk_size is down to 788MiB. The next step in the code is to search for max_stripe_size * dev_stripes amount of free space on the device, which is in our example 1GiB * 2 = 2GiB. Imagine the device has exactly 1578MiB free in one contiguous piece. This amount of bytes will be put in devices_info[ndevs - 1].max_avail Next we recalculate the stripe_size (which is actually the device extent length), based on the actual maximum amount of available raw disk space: stripe_size = div_u64(devices_info[ndevs - 1].max_avail, dev_stripes); stripe_size is now 789MiB Next we do... data_stripes = num_stripes / ncopies ...where data_stripes ends up as 1, because num_stripes is 2 (the amount of device extents we're going to have), and DUP has ncopies 2. Next there's a check... if (stripe_size * data_stripes > max_chunk_size) ...which matches because 789MiB * 1 > 788MiB. We go into the if code, and next is... stripe_size = div_u64(max_chunk_size, data_stripes); ...which resets stripe_size to max_chunk_size: 788MiB Next is a fun one... /* bump the answer up to a 16MB boundary */ stripe_size = round_up(stripe_size, SZ_16M); ...which changes stripe_size from 788MiB to 800MiB. We're not done changing stripe_size yet... /* But don't go higher than the limits we found while searching * for free extents */ stripe_size = min(devices_info[ndevs - 1].max_avail, stripe_size); This is bad. max_avail is twice the stripe_size (we need to fit 2 device extents on the same device for DUP). The result here is that 800MiB < 1578MiB, so it's unchanged. However, the resulting DUP chunk will need 1600MiB disk space, which isn't there, and the second dev_extent might extend into the next thing (next dev_extent? end of device?) for 22MiB. The last shown line of code relies on a situation where there's twice the value of stripe_size present as value for the variable stripe_size when it's DUP. This was actually the case before commit 92e222df "btrfs: alloc_chunk: fix DUP stripe size handling", from which I quote: "[...] in the meantime there's a check to see if the stripe_size does not exceed max_chunk_size. Since during this check stripe_size is twice the amount as intended, the check will reduce the stripe_size to max_chunk_size if the actual correct to be used stripe_size is more than half the amount of max_chunk_size." In the previous version of the code, the 16MiB alignment (why is this done, by the way?) would result in a 50% chance that it would actually do an 8MiB alignment for the individual dev_extents, since it was operating on double the size. Does this matter? Does it matter that stripe_size can be set to anything which is not 16MiB aligned because of the amount of remaining available disk space which is just taken? What is the main purpose of this round_up? The most straightforward thing to do seems something like... stripe_size = min( div_u64(devices_info[ndevs - 1].max_avail, dev_stripes), stripe_size ) ..just putting half of the max_avail into stripe_size."

We have a complex loop design for find_free_extent(), that has different behavior for each loop, some even includes new chunk allocation. Instead of putting such a long code into find_free_extent() and makes it harder to read, just extract them into find_free_extent_update_loop(). With all the cleanups, the main find_free_extent() should be pretty barebone: find_free_extent() |- Iterate through all block groups | |- Get a valid block group | |- Try to do clustered allocation in that block group | |- Try to do unclustered allocation in that block group | |- Check if the result is valid | | |- If valid, then exit | |- Jump to next block group | |- Push harder to find free extents |- If not found, re-iterate all block groups Signed-off-by:

Instead of tons of different local variables in find_free_extent(), extract them into find_free_extent_ctl structure, and add better explanation for them. Some modification may looks redundant, but will later greatly simplify function parameter list during find_free_extent() refactor. Also add two comments to co-operate with fb5c39d7 ("btrfs: don't use ctl->free_space for max_extent_size"), to make ffe_ctl->max_extent_size update more reader-friendly. Signed-off-by:

Qu Wenruo authored
Although we have space_info::bytes_may_use underflow detection in btrfs_free_reserved_data_space_noquota(), we have more callers who are subtracting number from space_info::bytes_may_use. So instead of doing underflow detection for every caller, introduce a new wrapper update_bytes_may_use() to replace open coded bytes_may_use modifiers. This also introduce a macro to declare more wrappers, but currently space_info::bytes_may_use is the mostly interesting one. Reviewed-by:

Tracking pending ordered extents per transaction was introduced in commit 50d9aa99 ("Btrfs: make sure logged extents complete in the current transaction V3") and later updated in commit 161c3549 ("Btrfs: change how we wait for pending ordered extents"). However now that on fsync we always wait for ordered extents to complete before logging, done in commit 5636cf7d ("btrfs: remove the logged extents infrastructure"), we no longer need the stuff to track for pending ordered extents, which was not completely removed in the mentioned commit. So remove the remaining of the pending ordered extents infrastructure. Reviewed-by:

The logged_start and logged_end variables, at btrfs_log_changed_extents, were added in commit 8c6c5928 ("btrfs: log csums for all modified extents"). However since the recent simplification for fsync, which makes us wait for all ordered extents to complete before logging extents, we no longer need those variables. Commit a2120a47 ("btrfs: clean up the left over logged_list usage") forgot to remove them. Reviewed-by:

The spdxcheck script currently falls over when confronted with a binary file (such as Documentation/logo.gif). To avoid that, always open files in binary mode and decode line-by-line, ignoring encoding errors. One tricky case is when piping data into the script and reading it from standard input. By default, standard input will be opened in text mode, so we need to reopen it in binary mode. The breakage only happens with python3 and results in a UnicodeDecodeError (according to Uwe).

There is actually a space after "sp," like this, ffff2000080813c8: a9bb7bfd stp x29, x30, [sp, #-80]! Right now, checkstack.pl isn't able to print anything on aarch64, because it won't be able to match the stating objdump line of a function due to this missing space. Hence, it displays every stack as zero-size. After this patch, checkpatch.pl is able to match the start of a function's objdump, and is then able to calculate each function's stack correctly.

Piotr Jaroszynski authored
migrate_page_move_mapping() expects pages with private data set to have a page_count elevated by 1. This is what used to happen for xfs through the buffer_heads code before the switch to iomap in commit 82cb1417 ("xfs: add support for sub-pagesize writeback without buffer_heads"). Not having the count elevated causes move_pages() to fail on memory mapped files coming from xfs. Make iomap compatible with the migrate_page_move_mapping() assumption by elevating the page count as part of iomap_page_create() and lowering it in iomap_page_release(). It causes the move_pages() syscall to misbehave on memory mapped files from xfs. It does not not move any pages, which I suppose is "just" a perf issue, but it also ends up returning a positive number which is out of spec for the syscall. Talking to Michal Hocko, it sounds like returning positive numbers might be a necessary update to move_pages() anyway though (https://lkml.kernel.org/r/20181116114955.GJ14706@dhcp22.suse.cz). I only hit this in tests that verify that move_pages() actually moved the pages. The test also got confused by the positive return from move_pages() (it got treated as a success as positive numbers were not expected and not handled) making it a bit harder to track down what's going on.

A stack trace was triggered by VM_BUG_ON_PAGE(page_mapcount(page), page) in free_huge_page(). Unfortunately, the page->mapping field was set to NULL before this test. This made it more difficult to determine the root cause of the problem. Move the VM_BUG_ON_PAGE tests earlier in the function so that if they do trigger more information is present in the page struct.

The conversion of alpha to memblock as the early memory manager caused boot to hang as described at [1]. The issue is caused because for CONFIG_DISCTONTIGMEM=y case, memblock_add() is called using memory start PFN that had been rounded down to the nearest 8Mb and it caused memblock to see more memory that is actually present in the system. Besides, memblock allocates memory from high addresses while bootmem was using low memory, which broke the assumption that early allocations are always accessible by the hardware. This patch ensures that memblock_add() is using the correct PFN for the memory start and forces memblock to use bottom-up allocations.

Specifying a starting ID greater than the maximum ID isn't something attempted very often, but it should fail. It was succeeding due to xas_find_marked() returning the wrong error state, so add tests for both xa_alloc() and xas_find_marked(). Fixes: b803b428 ("xarray: Add XArray iterators") Signed-off-by:

Pull rdma fixes from Doug Ledford: "We have 5 small fixes for this pull request. One is a performance regression, so not necessarily strictly a fix, but it was small and reasonable and claimed to avoid thrashing in the scheduler, so I took it. The remaining are all legitimate fixes that match the "we take fixes any time" criteria. Summary: - One performance regression for hfi1 - One kasan fix for hfi1 - A couple mlx5 fixes - A core oops fix" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: IB/core: Fix oops in netdev_next_upper_dev_rcu() IB/mlx5: Block DEVX umem from the non applicable cases IB/mlx5: Fix implicit ODP interrupted page fault IB/hfi1: Fix an out-of-bounds access in get_hw_stats IB/hfi1: Fix a latency issue for small messages
