Subject: [GIT PULL] block bits for 2.6.34-rc1
Hi Linus,
Nothing earth shattering in here:
- Various tweaks to CFQ, mostly a few performance tweaks.
- cciss driver update
- Cleanup/unification of the max transfer size setting for drivers, this
was left in a bit of a mess after the io limits patches.
- Switch block core and pktcdvd to using the bio list instead of doing
they own list management.
- Modify the 'nomerges' sysfs knob to be able to completely turn off
merges. We used to have 0/1 possibilities, but even with nomerges==1,
we would check and perform last_hit merges. For testing, it's useful
to disable even that bit. The new value '2' turns off all merging.
- Various other small patchlets.
Please pull.
