. Some rework and restructuring of the anticipatory scheduling code.
The reported slowdown in RAID1 rebuild _may_ have been fixed. At least,
it doesn't happen for me with this patchset.
. The request aliasing problem hasn't been fixed yet, so this kernel (and
2.5.59) will still fail under heavy direct-IO load.
. The mysterious "machine hangs late in boot" problem has been narrowed
down thanks to some great work by Andres Salomon. The machine is stuck
waiting on I/O completion when performing the initial lookup for

Which _looks_ like a request queueing problem, but Andres says it goes
away when devfs is disabled in config. So I've dropped the smalldevfs
patch for now - would be appreciated if devfs users could retest this
patch, with CONFIG_DEVFS=y.
. There appears to be a CPU utilisation problem with
reiserfs_file_write.patch - but it doesn't oops or corrupt data so I've
left that in for now while Oleg scratches his head over that one.
