Merge branch 'for-2.6.37/drivers' of git://git.kernel.dk/linux-2.6-block
* 'for-2.6.37/drivers' of git://git.kernel.dk/linux-2.6-block: (95 commits) cciss: fix PCI IDs for new Smart Array controllers drbd: add race-breaker to drbd_go_diskless drbd: use dynamic_dev_dbg to optionally log uuid changes dynamic_debug.h: Fix dynamic_dev_dbg() macro if CONFIG_DYNAMIC_DEBUG not set drbd: cleanup: change "<= 0" to "== 0" drbd: relax the grace period of the md_sync timer again drbd: add some more explicit drbd_md_sync drbd: drop wrong debug asserts, fix recently introduced race drbd: cleanup useless leftover warn/error printk's drbd: add explicit drbd_md_sync to drbd_resync_finished drbd: Do not log an ASSERT for P_OV_REQUEST packets while C_CONNECTED drbd: fix for possible deadlock on IO error during resync drbd: fix unlikely access after free and list corruption drbd: fix for spurious fullsync (uuids rotated too fast) drbd: allow for explicit resync-finished notifications drbd: preparation commit, using full state in receive_state() drbd: drbd_send_ack_dp must not rely on header information drbd: Fix regression in recv_bm_rle_bits (compressed bitmap) drbd: Fixed a stupid copy and paste error drbd: Allow larger values for c-fill-target. ... Fix up trivial conflict in drivers/block/ataflop.c due to BKL removal
