Hi Linus,
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.
Please pull!
