This makes mpage use bio_add_page(). It has the added advantage that users don't need to have deep knowledge about what the different bio fields mean, nor does it have to abuse some of them while building the bio.

This is bio_add_page(), 100% identical to the version I sent out for comments earlier this week. With the previous queue restriction patch, this guarentees that we can always add a page worth of data to the bio. bio_add_page() returns 0 on success, and 1 on failure. Either the page is added completely, or the attempt is aborted. bio_add_page() uses the normal queue restrictions to determine whether we an add the page or not. if a queue has further restrictions, it can define a q->merge_bvec_fn() to further impose limits. Patch also includes changes to ll_rw_kio(), if for nothing else to demonstrate how to use this piece of instrastructure.

Impose sane limits on queue restrictions. that means: - q->max_sectors must be able to at least span a page - q->max_phys_segments and q->max_hw_segments must be at least 1 - q->max_segment_size must be at least page sized - q->seg_boundary_mask must be at least PAGE_CACHE_SIZE-1

cyclades.c doesn't compile cleanly: the problem is that older -dj patches contained patches to both cyclades.c and cyclades.h but only the former one went into your tree. This syncs up the header file too.

Here's a resend of C99 patches for the files in fs.

The old form of designated initializers are obsolete: we need to replace them with the ISO C forms before 2.6. Gcc has always supported both forms anyway.

I suck. Lvalues continue to haunt me. This works for me. BTW, I prefer to have bug reports cc'd to linux-kernel, so the results are archived. Plus, public humiliation is good for the soul.

This is a trivial patch already applied in the -ac tree for the 2.4.19 kernel. Patch for i2c-philips-par.c free() the memory in the case of problems loading the adapter.

<linux/smp_lock.h> has the normal idempotent construction. The attached file removes the second #include.

Here's a C99 designated initializer patch for fs/freevxfs. The patch is against 2.5.35.

Display the total slab memory in /proc/meminfo. Handy while we play with the slab pruning code. This info is also available via /proc/slabinfo, but I think this convenience is worth the extra few lines.

Patch from Christoph Hellwig. Move the buffer_head-based IO functions out of ll_rw_blk.c and into fs/buffer.c. So the buffer IO functions are all in buffer.c, and ll_rw_blk.c knows nothing about buffer_heads. This patch has been acked by Jens.

From Anton Altaparmakov The below bk patch against your current bk repository adds an export for fs/buffer.c::unmap_underlying_metadata() to modules. It is required to make ntfs compile as a module in the current kernel. Note that NTFS doesn't currently dirty bufferheads of the underlying blockdevice and as such could probably live without calling unmap_underlying_metadata() but as soon as we enable writing to compressed files it will do so and considering some of the infrastructure code is already present I would rather not rip it out now.

Patch by Christoph Hellwig. This patch is cleanup of mmap.c with the side-effect of making the lock order of mapping->i_shared_lock and mm->page_table_lock consistant. __remove_shared_vm_struct is merged into its only caller, remove_shared_vm_struct, which now also does the job of {lock,unlock}_vma_mappings itself, to avoid duplicate checks. Similarly, vma_link is updated to take and release i_shared_lock itself, fixing the lock order. split_vma is updated to use insert_vm_struct instead of using __insert_vm_struct and taking page_table_lock and i_shared_lock itself (wrongly). __insert_vm_struct is removed as it is unused now.

Patch from Christoph Hellwig. 250 lines of code go away. The three syscalls madvice/mlock/mprotect all change attributes of memory regions. These attributes are stored in vm_area_structs (VMAs). The current code for those syscalls does this by having four subroutines each, for changing a whole VMA, one for just setting new flags if a full VMA is affected, one that creates a new VMA in the right part of the old one and sets the flags there, one for the left part, and one that splits of both the left and the right part and sets the new flags in the middle. This patch makes those routines create new VMAs on the left and on te right hand first and then always setting the flags in the old VMA. Together with using a library function (split_vma) to to the split this simplies the code and makes it more readable. As a side affect it fixes some VM accounting bugs observed by Hugh Dickins.

Patch from Christoph Hellwig moves the madvise implementation out of filemap.c and into its own .c file. No other changes are made.

Andrew removed a flush_dcache_page in his kmap_atomic generic_file_* changes. Doing that sort of corrupts data on some platforms.

Now that all archs use the same way to generate the link script, we can handle it from the common top-level Makefile instead of the individual arch/*/Makefile's.

This is an untested attempt to convert ARM to preprocessing vmlinux.lds.S instead of running sed on it - This probably allows for further cleanup, but I'll leave that to _rmk_.
-
Kai Germaschewski authored
For consistency reasons, generate arch/$(ARCH)/vmlinux.lds.s from arch/$(ARCH)/vmlinux.lds.S on all archs, even those which do not need preprocessing (yet).

Sam Ravnborg: Yep, "if_changed_dep" uses fixdep, so a dependency to scripts is needed. Added echo_target as well, so the result file is printed as well.
