Subject: [PATCH for-4.2 00/14] block, dm: first batch of changes for 4.2
Here is the start of the DM changes I've queued for 4.2 (via
linux-dm.git's for-next branch).
I'm posting them to the lists mainly to get feedback on the block
changes (first 4 patches) and to publish Joe's dm-thinp discard
improvements which depend on the new blkdev_issue_discard_async
interface.
Jens, if all looks OK please pick up the first 4 block patches. The
"block: remove management of bi_remaining when restoring original
bi_end_io" has been tested in terms of DM. I haven't tested btrfs,
bcache, etc.
All review/feedback is welcome. Thanks!
Mike
