* [PATCH] BLOCK: Dissociate generic_writepages() from mpage stuff [try #6]David Howells2006-09-302-0/+3
| | | | | | | | | | | | | | Dissociate the generic_writepages() function from the mpage stuff, moving its declaration to linux/mm.h and actually emitting a full implementation into mm/page-writeback.c. The implementation is a partial duplicate of mpage_writepages() with all BIO references removed. It is used by NFS to do writeback.

* [PATCH] BLOCK: Remove dependence on existence of blockdev_superblock [try #6]David Howells2006-09-302-3/+5
| | | | | | | | Move blockdev_superblock extern declaration from fs/fs-writeback.c to a headerfile and remove the dependence on it by wrapping it in a macro. Signed-Off-By: David Howells <dhowells@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
* [PATCH] BLOCK: Move extern declarations out of fs/*.c into header files [try #6]David Howells2006-09-309-17/+44
| | | | | | | | | | | Create a new header file, fs/internal.h, for common definitions local to the sources in the fs/ directory. Move extern definitions that should be in header files from fs/*.c to fs/internal.h or other main header files where they span directories.

* [PATCH] BLOCK: Don't call block_sync_page() from AFS [try #6]David Howells2006-09-301-1/+0

* [PATCH] BLOCK: Move functions out of buffer code [try #6]David Howells2006-09-303-174/+144
| | | | | | | | | | | | | | | | | | | | | | | | | Move some functions out of the buffering code that aren't strictly buffering specific. This is a precursor to being able to disable the block layer. (*) Moved some stuff out of fs/buffer.c: (*) The file sync and general sync stuff moved to fs/sync.c. (*) The superblock sync stuff moved to fs/super.c. (*) do_invalidatepage() moved to mm/truncate.c. (*) try_to_release_page() moved to mm/filemap.c. (*) Moved some related declarations between header files: (*) declarations for do_invalidatepage() and try_to_release_page() moved to linux/mm.h. (*) __set_page_dirty_buffers() moved to linux/buffer_head.h. Signed-Off-By: David Howells <dhowells@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>

* [PATCH] cfq-iosched: kill cfq_exit_lockJens Axboe2006-09-301-2/+2
| | | | | | | | | | | | | | | | | | | | | cfq_exit_lock is protecting two things now: - The per-ioc rbtree of cfq_io_contexts - The per-cfqd linked list of cfq_io_contexts The per-cfqd linked list can be protected by the queue lock, as it is (by definition) per cfqd as the queue lock is. The per-ioc rbtree is mainly used and updated by the process itself only. The only outside use is the io priority changing. If we move the priority changing to not browsing the rbtree, we can remove any locking from the rbtree updates and lookup completely. Let the sys_ioprio syscall just mark processes as having the iopriority changed and lazily update the private cfq io contexts the next time io is queued, and we can remove this locking as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous attempts to fix the linux inode use-after-free in xfs_iunpin simply made the problem harder to hit. We actually need complete exclusion between xfs_reclaim and xfs_iunpin, as well as ensuring that the i_flags are consistent during both of these functions. Introduce a new spinlock for exclusion and the i_flags, and fix up xfs_iunpin to use igrab before marking the inode dirty.
