Updated lockless pagecache patchset available here:
ftp://ftp.kernel.org/pub/linux/kernel/people/npiggin/patches/lockless/2.6.17/lockless.patch.gz
This should hopefully be my last release using the old (2.6.17)
indirect radix-tree, and I'll switch to the direct radix-tree in
future.
Changes since last release:
- lots of radix-tree cleanups and bugs fixed
- radix-tree tag lookups may be lockless
- added some missing memory barriers
- lockless pagevec_lookup_tag
The last item allowed me to remove the last few read-lockers,
which is nice.

Sorry for noise - it's 2.6.17 problem. I didn't notice this.
