While commiting items looks very similar to freeing them on error it is a different operation, and they will diverge a bit soon. Split out the commit case from xfs_trans_free_items, inline it into xfs_log_commit_cil and give it a separate trace point. Signed-off-by:

Now that we don't use struct xfs_buf to hold log recovery buffer rename the related functions and variables to just talk of a buffer instead of using the bp name that we usually use for xfs_buf related functionality. Signed-off-by:

The xfs_buf structure is basically used as a glorified container for a memory allocation in the log recovery code. Replace it with a call to kmem_alloc_large and a simple abstraction to read into or write from it synchronously using chained bios. Signed-off-by:

This simplifies both the helper and the callers. We lost a bit of size sanity checking, but that is already covered by KASAN if needed. Signed-off-by:

Move the workqueue used for log I/O completions from struct xfs_mount to struct xlog to keep it self contained in the log code. Signed-off-by:

Currently the XFS logging code uses the xfs_buf structure and associated APIs to write the log buffers to disk. This requires various special cases in the log code and is generally not very optimal. Instead of using a buffer just allocate a kmem_alloc_larger region for each log buffer, and use a bio and bio_vec array embedded in the iclog structure to write the buffer to disk. This also allows for using the bio split and chaining case to deal with the case of a log buffer wrapping around the end of the log. Signed-off-by:

Split out a self-contained chunk of code from xlog_sync that calculates the split offset for an iclog that wraps the log end and bumps the cycles for the second half. Use the chance to bring some sanity to the variables used to track the split in xlog_sync by not changing the count variable, and instead use split as the offset for the split and use those to calculate the sizes and offsets for the two write buffers.

Replace the not very useful xlog_bdstrat wrapper with a new version that that takes care of all the common logic for writing log buffers. Use the opportunity to avoid overloading the buffer address with the log relative address, and to shed the unused return value. Signed-off-by:

If we have to split a log write because it wraps the end of the log we can't just use REQ_PREFLUSH to flush before the first log write, as the writes might get reordered somewhere in the I/O stack. Issue a manual flush in that case so that the ordering of the two log I/Os doesn't matter. Signed-off-by:

This value is the only flag in ic_state, which we otherwise use as a state. Switch it to a new debug-only field and also report and actual error in the buffer in the I/O completion path. Signed-off-by:

We don't really need all the messy branches in the function, as it really does three things, out of which 2 are common for all branches: 1) set up mount point log buffer size and count values if not already done from mount options 2) calculate the number of log headers 3) set up all the values in struct xlog based on the above Signed-off-by: -

The XFS_BUILD_OPTIONS string, shown at module init time and in modinfo output, does not currently include all available build options. So, add in CONFIG_XFS_WARN and CONFIG_XFS_REPAIR. It has been suggested in some quarters That this is not enough. Well ... Anybody who would like to see this in a sysfs file can send a patch. :) Signed-off-by:

Darrick J. Wong authored
inode_cluster_size is supposed to represent the size (in bytes) of an inode cluster buffer. We avoid having to handle multiple clusters per filesystem block on filesystems with large blocks by openly rounding this value up to 1 FSB when necessary. However, we never reset inode_cluster_size to reflect this new rounded value, which adds to the potential for mistakes in calculating geometries. Fix this by setting inode_cluster_size to reflect the rounded-up size if needed, and special-case the few places in the sparse inodes code where we actually need the smaller value to validate on-disk metadata.
