Subject2.5.59-mm7

http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.59/2.5.59-mm7/

. I've split the anticipatory scheduling code out into the experimental/
directory. We need to get the base I/O scheduler settled down and working
well. Various bad things have happened to it in recent months.

The I/O scheduler in this patchset should perform quite well.

. Futexes, direct-io and ptrace peek/poke into hugetlb pages were all
quite broken. Should be fixed up here.



Changes since 2.5.59-mm6:


+devfs-fix.patch

Bring the devfs mount-at-boot fix back.

+batch-tuning.patch

I/O scheduler tuning - split up the read and write batching settings, pick
sane values.

+starvation-by-read-fix.patch

Fix the reads-starve-everything problem.

+smaller-slab-batches.patch

Fix a problem wherein slab activity can disable interrupts for too long
when slab debug is enabled.

+printk-locking.patch

-anticipatory_io_scheduling-2_5_59-mm3.patch

work (spotted by Rik).
