There's some work here to address some of the whacky corner cases
which have traditionally knocked the VM over. Some are fixed, some
still need work. My latest party trick is to run a 4G highmem machine
with 800 megabytes of ZONE_NORMAL under mlock. Can't say that it
completely works yet...
Of note in -mm2 is a patch from Chris Mason which teaches reiserfs to
use the mpage code for reads - it should show a nice reduction in CPU
load under reiserfs reads.
And Jens's rbtree-based insertion code for the request queue. Which
means that the queues can be grown a *lot* if people want to play with
that. The VM should be able to cope with it fine.
And a new set of block a_ops which never, ever, ever attach buffer_heads
to file pagecache. Implemented for ext2 - use `mount -o nobh'.
And several VM tuning and stability tweaks.
