Subject[GIT PULL] block/IO bits for 2.6.36-rc1
Hi Linus,

This is the big round of updates for the IO bits for 2.6.36-rc1.
Not sure what happened on the excessive number of merges listed
as:

Merge branch 'for-2.6.36' into for-next

as these should 1) just have been regular fast forwards, and 2)
not be listed under 2.6.36 when the pull was in the other
direction. I tend to run -git git versions, so perhaps there
was a bad version in there. I was planning on reshuffling
the branch, but it's 3 months of churn and fixups in there and
that would take me a while. Let me know if you absolutely
hate it and I'll do it.

Anyway, summary of changes:

- The block parts of the BKL removal from Arnd.

- The race fixing and wakeup appeasing writeback thread
cleanups/fixes from Artem. Originally done to be easier
on the power consumption, but Artem also found and fixed
some races on the exiting writeback task part.

- The writeback cleanups from Christoph.

- The writeback tracing bits from David Chinner, which
allow us to trace and inspect whether things are doing
as we inspect.

- Also from Christoph is the unification of the bio
and request flags and removal of the flag wrappers,
which makes things more readable and maintainable.

- Fixes from Tejun so that the read-ahead and sync WRITE
bits match up again. Also puts the bio read/write bits
into a separate header file.

- Two fixes for splice, alsoing going into stable.

- Series update of the blkfront driver.

- Series update of the CCISS driver.

- Removal of the ancient ISA_DMA_THRESHOLD in block/scsi
from Tomo. This is the arch/ churn in this patch series.

- Also from Tomo is the nice cleanup of the empty barrier
code and the conversion of barriers to be regular file
system request instead of block PC requests.

- A fix for the discard handling, making sure that we
don't traverse back into the file system on allocation.

- drbd gets a feature reverted that apparently wasn't
well enough tested. This is also going into stable. A
few other fixes for drbd as well.

- The floppy cleanup series from Stephen.

- And the usual string of little cleanups/fixes from a
bunch of other people.


Please pull!
