[GIT PULL] block tree for 2.6.35
From: Jens Axboe
Date: Fri May 21 2010 - 15:20:37 EST
Hi Linus,
This is the initial (and big) part of the bits stashed in the block git
tree for 2.6.35.
- A good bunch of IO controller updates. I apologize for the quality of
the changelog for those, I should have caught that in due time. Will
not happen again.
- Updates and additions to the discard requests.
- A big drbd update.
- Fixes for a few writeback bugs and regressions.
- The pipe grow/shrink support with the default 256 page limit and
a proc file for root to modify that limit.
- Make laptop mode per-device instead of a global setting.
- And of course a good bunch of bug fixes.
Please pull.

blkio: Remove per-cfqq nr_sectors as we'll be passing
blkio: Add io controller stats like
blkio: Increment the blkio cgroup stats for real now
blkio: Changes to IO controller additional stats patches
blkio: Add io_merged stat
blkio: Add io_queued and avg_queue_size stats
blkio: Add more debug-only per-cgroup stats
block: Update to io-controller stats
blkio: Fix compile errors
blkio: fix for modular blk-cgroup build
blkio: Initialize blkg->stats_lock for the root cfqg too
Dmitry Monakhov (6):
blkdev: generalize flags for blkdev_issue_fn functions
blkdev: allow async blkdev_issue_flush requests
blkdev: move blkdev_issue helper functions to separate file
blkdev: add blkdev_issue_zeroout helper function
cfq-iosched: fix broken cfq_ref_get_cfqf() for CONFIG_BLK_CGROUP=y && CFQ_GROUP_IOSCHED=n
writeback: Update dirty flags in two steps
Gui Jianfeng (2):
io-controller: Add a new interface "weight_device" for IO-Controller
io-controller: Document for blkio.weight_device
Jens Axboe (14):
Merge branch 'for-linus' into for-2.6.35
Merge branch 'master' into for-2.6.35
block: fix bad use of min() on different types
Merge branch 'master' into for-2.6.35
block: kill some useless goto's in blk-cgroup.c
writeback: disable periodic old data writeback for !dirty_writeback_centisecs
writeback: fix WB_SYNC_NONE writeback from umount
writeback: ensure that WB_SYNC_NONE writeback with sb pinned is sync
writeback: bdi_writeback_task() must set task state before calling schedule()
writeback: fixups for !dirty_writeback_centisecs
writeback: fix problem with !CONFIG_BLOCK compilation
writeback: fix mixed up arguments to bdi_start_writeback()
pipe: add support for shrinking and growing pipes
pipe: set lower and upper limit on max pages in the pipe page array
Julia Lawall (1):
drivers/block/drbd: Use kzalloc
Lars Ellenberg (11):
drbd: use proc_create_data with explicit NULL argument
drbd: fix regression: attach while connected failed
drbd: remove bogus ASSERT
drbd: fix potential protocol error
drbd: don't start a resync without access to up-to-date Data

drbd: fail_requests_early: remove incorrect and unnecessary optimization
drbd: reduce sizeof struct drbd_epoch_entry by 8 byte by aligning members
drbd: Allow drbd_epoch_entries to use multiple bios. This should allow for better performance if the lower level IO stack of the peers differs in limits exposed either via the queue, or via some merge_bvec_fn.
drbd: allow resync requests to be larger than max_segment_size
drbd: always use_bmbv, ignore setting
Matthew Garrett (1):

block: remove all rcu head initializations
Philipp Reisner (27):
drbd: Do not upgrade state to Outdated if already Inconsistent [Bugz 277]
drbd: cleanup: This code path to trigger a resync is no longer needed
drbd: made determin_dev_size's parameter an flag enum
drbd: Implemented the set_new_bits parameter for drbd_bm_resize()
drbd: Implemented flags for the resize packet
drbd: Make sure to resync all of the new storage upon online resize
drbd: Added some missing statics
drbd: Implemented the --assume-clean option for drbdsetup resize
drbd: bugfix: Make resize work, if remote's size was limiting and increased in the meantime
drbd: Added transmission faults to the fault injection code
drbd: Fixed bitmap in case of online-grow without resync
drbd: Receiving of delay_probes
drbd: Sending of delay_probes
drbd: Four new configuration settings for resync speed control
drbd: Actually send delay probes
drbd: Control the actual resync rate based on the queuing delay of data packets
drbd: Proc bits of new resync speed stuff
drbd: A fixes to the new resync speed code
drbd: Fixes to the new delay_probes code
drbd: If we detect late that IO got frozen, retry after we thawed.
drbd: Create new current UUID as late as possible
drbd: Do not Oops when C_STANDALONE when uuid gets generated
drbd: Ensure to not trigger late-new-UUID creation multiple times
drbd: Fix: Do not detach, if a bio with a barrier fails
drbd: Null pointer deref fix to the large "multi bio rewrite"
drbd: Do not free p_uuid early, this is done in the exit code of the receiver
drbd: This is now equivalent to drbd release 8.3.8rc1
