Merge branch 'for-3.14/core' of git://git.kernel.dk/linux-block

2014-01-30T19:19:05Z

Pull core block IO changes from Jens Axboe: "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" * 'for-3.14/core' of git://git.kernel.dk/linux-block: (44 commits) xtensa: fixup simdisk driver to work with immutable bio_vecs block/blk-mq-cpu.c: use hotcpu_notifier() blk-mq: for_each_* macro correctness block: Fix memory leak in rw_copy_check_uvector() handling bio-integrity: Fix bio_integrity_verify segment start bug block: remove unrelated header files and export symbol blk-mq: uses page->list incorrectly blk-mq: use __smp_call_function_single directly btrfs: fix missing increment of bi_remaining Revert "block: Warn and free bio if bi_end_io is not set" block: Warn and free bio if bi_end_io is not set blk-mq: fix initializing request's start time block: blk-mq: don't export blk_mq_free_queue() block: blk-mq: make blk_sync_queue support mq block: blk-mq: support draining mq queue dm cache: increment bi_remaining when bi_end_io is restored block: fixup for generic bio chaining block: Really silence spurious compiler warnings block: Silence spurious compiler warnings block: Kill bio_pair_split() ...

f2fs: refactor bio-related operations

2013-12-23T01:18:05Z

This patch integrates redundant bio operations on read and write IOs. 1. Move bio-related codes to the top of data.c. 2. Replace f2fs_submit_bio with f2fs_submit_merged_bio, which handles read bios additionally. 3. Introduce __submit_merged_bio to submit the merged bio. 4. Change f2fs_readpage to f2fs_submit_page_bio. 5. Introduce f2fs_submit_page_mbio to integrate previous submit_read_page and submit_write_page.

f2fs: add detailed information of bio types in the tracepoints

2013-12-23T01:18:03Z

This patch inserts information of bio types in more detail. So, we can now see REQ_META and REQ_PRIO too. Signed-off-by: Jaegeuk Kim
