2.6.8 was released August 14, 2004. Changelog

• Allow x86 to reenable interrupts on lock contention (commit)

• Add O_NOATIME open(2) flag support (GNU extension): If this bit is set, read will not update the access time of the file. It is useful if you want to do something with the file atime (for instance, moving files that have not been accessed in a while to somewhere else, or something like Debian's popularity-contest) but you also want to read all files periodically (for instance, tripwire or debsums) commit

• VFS shrinkage tuning: This adds /proc/sys/vm/vfs_cache_pressure, which tunes the vfs cache versus pagecache scanning pressure. At vfs_cache_pressure=0 we don't shrink dcache and icache at all, at vfs_cache_pressure=100 there is no change in behaviour, at vfs_cache_pressure > 100 we reclaim dentries and inodes harder commit

• MNT_EXPIRE for umount(): Intrinsic automount and mountpoint degradation support. This adds support for a filesystem (such as kAFS) to perform automounting intrinsically without the need for a userspace daemon. It also adds support for such mountpoints to be degraded at the filesystem's behest until they've been untouched long enough that they'll be removed commit, commit

• Conversion to the new symbolic link resolution code (which will eventually allow an increase in the maximum link depth) (LWN article). commit, commit, commit, commit, commit, commit, commit, commit, commit
