[PATCH] add AOP_TRUNCATED_PAGE, prepend AOP_ to WRITEPAGE_ACTIVATE

2006-01-03T19:45:42Z

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

[PATCH] readahead commentary

2005-11-07T15:53:37Z

Add a few comments surrounding the generic readahead API. Also convert some ulongs into pgoff_t: the identifier for PAGE_CACHE_SIZE offsets into pagecache. Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] readahead: reset cache_hit earlier

2005-09-07T23:57:25Z

We don't reset the cache hit count until after readahead does a successful readahead. This seems to leave a corner case open where we miss in cache, but don't restart the readhead right away. Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

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!
