Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe: "Make the block layer great again. Basically three amazing fixes in this pull request, split into 4 patches. Believe me, they should go into 4.4. Two of them fix a regression, the third and last fixes an easy-to-trigger bug. - Fix a bad irq enable through null_blk, for queue_mode=1 and using timer completions. Add a block helper to restart a queue asynchronously, and use that from null_blk. From me. - Fix a performance issue in NVMe. Some devices (Intel Pxxxx) expose a stripe boundary, and performance suffers if we cross it. We took that into account for merging, but not for the newer splitting code. Fix from Keith. - Fix a kernel oops in lightnvm with multiple channels. From Matias" * 'for-linus' of git://git.kernel.dk/linux-block: lightnvm: wrong offset in bad blk lun calculation null_blk: use async queue restart helper block: add blk_start_queue_async() block: Split bios on chunk boundaries
