[PATCH] relative atime
Add "relatime" (relative atime) support. Relative atime only updates the atime if the previous atime is older than the mtime or ctime. Like noatime, but useful for applications like mutt that need to know when a file has been read since it was last modified. A corresponding patch against mount(8) is available at http://userweb.kernel.org/~akpm/mount-relative-atime.txt Signed-off-by: Valerie Henson <val_henson@linux.intel.com> Cc: Mark Fasheh <mark.fasheh@oracle.com> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Christoph Hellwig <hch@lst.de> Cc: Karel Zak <kzak@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
