Subject: [GIT PULL] Core block IO changes for 3.14
Hi Linus,
This is the pull request for the core block IO changes for 3.14. The
major piece in here is the immutable bio_ve series from Kent, the rest
is fairly minor. It was supposed to go in last round, but various issues
pushed it to this release instead. The pull request contains:
- Various smaller blk-mq fixes from different folks. Nothing major here,
just minor fixes and cleanups.
- Fix for a memory leak in the error path in the block ioctl code from
Christian Engelmayer.
- Header export fix from CaiZhiyong.
- Finally the immutable biovec changes from Kent Overstreet. This
enables some nice future work on making arbitrarily sized bios
possible, and splitting more efficient. Related fixes to immutable
bio_vecs:
- dm-cache immutable fixup from Mike Snitzer.
- btrfs immutable fixup from Muthu Kumar.
- bio-integrity fix from Nic Bellinger, which is also going to stable.
Please pull! There will be a bit of merge work for you, but it should be
fairly straight forward. It's mostly related to changin:
bio->bi_sector -> bio->bi_iter.bi_sector
bio->bi_size -> bio->bi_iter.bi_size
