[PATCH] BLOCK: Remove no-longer necessary linux/buffer_head.h inclusions [try #6]

2006-09-30T18:52:31Z

Remove inclusions of linux/buffer_head.h that are no longer necessary due to the transfer of a number of things out of there. Signed-Off-By: David Howells Signed-off-by: Jens Axboe

[PATCH] BLOCK: Don't call block_sync_page() from AFS [try #6]

2006-09-30T18:32:12Z

The AFS filesystem no longer needs to override its sync_page() op. Signed-Off-By: David Howells Signed-off-by: Jens Axboe

[PATCH] mark address_space_operations const

2006-06-28T21:59:04Z

Same as with already do with the file operations: keep them in .rodata and prevents people from doing runtime patching. Signed-off-by: Christoph Hellwig Cc: Steven French Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] Make address_space_operations->invalidatepage return void

2006-03-26T16:56:55Z

The return value of this function is never used, so let's be honest and declare it as void. Some places where invalidatepage returned 0, I have inserted comments suggesting a BUG_ON.

[PATCH] kfree cleanup: fs

2005-11-07T15:54:06Z

This is the fs/ part of the big kfree cleanup patch. Remove pointless checks for NULL prior to calling kfree() in fs/. Signed-off-by: Jesper Juhl Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] afs: use generic_ro_fops

2005-11-07T15:53:41Z

afs actually had a write method that returned different errors depending on whether some flag was set - better return the standard EINVAL errno. Signed-off-by: Christoph Hellwig Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] mm: split page table lock

2005-10-30T04:40:42Z

Christoph Lameter demonstrated very poor scalability on the SGI 512-way, with a many-threaded application which concurrently initializes different parts of a large anonymous area. This patch corrects that, by using a separate spinlock per page table page, to guard the page table entries in that page, instead of using the mm's single page_table_lock. (But even then, page_table_lock is still used to guard page table allocation, and anon_vma allocation.) In this implementation, the spinlock is tucked inside the struct page of the page table page: with a BUILD_BUG_ON in case it overflows - which it would in the case of 32-bit PA-RISC with spinlock debugging enabled. Splitting the lock is not quite for free: another cacheline access. Ideally, I suppose we would use split ptlock only for multi-threaded processes on multi-cpu machines; but deciding that dynamically would have its own costs. So for now enable it by config, at some number of cpus - since the Kconfig language doesn't support inequalities, let preprocessor compare that with NR_CPUS. But I don't think it's worth being user-configurable: for good testing of both split and unsplit configs, split now at 4 cpus, and perhaps change that to 8 later. There is a benefit even for singly threaded processes: kswapd can be attacking one part of the mm while another part is busy faulting.

[PATCH] gfp_t: fs/*

2005-10-28T15:16:47Z

- ->releasepage() annotated (s/int/gfp_t), instances updated - missing gfp_t in fs/* added - fixed misannotation from the original sweep caught by bitwise checks: XFS used __nocast both for gfp_t and for flags used by XFS allocator. The latter left with unsigned int __nocast; we might want to add a different type for those but for now let's leave them alone. That, BTW, is a case when __nocast use had been actively confusing - it had been used in the same code for two different and similar types, with no way to catch misuses. Switch of gfp_t to bitwise had caught that immediately... One tricky bit is left alone to be dealt with later - mapping->flags is a mix of gfp_t and error indications. Left alone for now.

[PATCH] Exterminate PAGE_BUG

Linux-2.6.12-rc2

2005-04-16T22:20:36Z

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
