2006-01-03[PATCH] add AOP_TRUNCATED_PAGE, prepend AOP_ to WRITEPAGE_ACTIVATEZach Brown
readpage(), prepare_write(), and commit_write() callers are updated to understand the special return code AOP_TRUNCATED_PAGE in the style of writepage() and WRITEPAGE_ACTIVATE. AOP_TRUNCATED_PAGE tells the caller that the callee has unlocked the page and that the operation should be tried again with a new page. OCFS2 uses this to detect and work around a lock inversion in its aop methods. There should be no change in behaviour for methods that don't return AOP_TRUNCATED_PAGE. WRITEPAGE_ACTIVATE is also prepended with AOP_ for consistency and they are made enums so that kerneldoc can be used to document their semantics. Signed-off-by: Zach Brown <zach.brown@oracle.com>
2005-10-08[PATCH] gfp flags annotations - part 1Al Viro
- added typedef unsigned int __nocast gfp_t; - replaced __nocast uses for gfp flags with gfp_t - it gives exactly the same warnings as far as sparse is concerned, doesn't change generated code (from gcc point of view we replaced unsigned int with typedef) and documents what's going on far better.

2005-06-04[PATCH] mpage_end_io_write() I/O error handling fixQu Fuping
When fsync() runs wait_on_page_writeback_range() it only inspects pages which are actually under I/O (PAGECACHE_TAG_WRITEBACK). If a page completed I/O prior to wait_on_page_writeback_range() looking at it, it is supposed to have recorded its I/O error state in the address_space. But mpage_mpage_end_io_write() forgot to set the address_space error flag in this case.

2005-05-05[PATCH] revert ext3-writepages-support-for-writeback-modeAndrew Morton
This had a fatal lock ranking bug: we do journal_start outside mpage_writepages()'s lock_page(). Revert the whole thing, think again. Credit-to: Jan Kara <jack@suse.cz> For identifying the bug.

2005-05-01[PATCH] mpage_writepages() page locking fixNikita Danilov
When ->writepage() returns WRITEPAGE_ACTIVATE, the page is still locked. Explicitly unlock the page in mpage_writepages(). Signed-off-by: Nikita Danilov <nikita@clusterfs.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

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!
