Block driver changes for 3.6

Hi Linus,

These are the driver bits for 3.6, based on (an earlier version) of for-3.6/core that I just asked you to pull. It contains:

- Making the plugging support for drivers a bit more sane from Neil. This supersedes the plugging change from Shaohua as well.
- The usual round of drbd updates.
- Using a tail add instead of a head add in the request completion for ndb, making us find the most completed request more quickly.
- A few floppy changes, getting rid of a duplicated flag and also running the floppy init async (since it takes forever in boot terms) from Andi.

Andi Kleen (1):
floppy: Run floppy initialization asynchronous

Chetan Loke (1):
block/nbd: micro-optimization in nbd request completion

Fengguang Wu (1):

Jens Axboe (3):
Merge branch 'upstream' of git://git.kernel.org/.../jikos/floppy into for-3.6/drivers Merge branch 'for-jens' of git://git.drbd.org/linux-drbd into for-3.6/drivers Merge branch 'upstream' of git://git.kernel.org/.../jikos/floppy into for-3.6/drivers

Lars Ellenberg (10):
drbd: cleanup, remove two unused global flags
drbd: differentiate between normal and forced detach
drbd: report congestion if we are waiting for some userland callback
drbd: reset congestion information before reporting it in /proc/drbd
drbd: do not reset rs_pending_cnt too early
drbd: call local-io-error handler early
drbd: fix potential access after free
drbd: flush drbd work queue before invalidate/invalidate remote
drbd: fix max_bio_size to be unsigned
drbd: announce FLUSH/FUA capability to upper layers
