Subject: [GIT PULL] Block changes for 4.9-rc1
Hi Linus,
Finally back from a bunch of travel and out-of-office. This is the main
pull request for block layer changes in 4.9. As mentioned at the last
merge window, I've changed things up and now do just one branch for core
block layer changes, and driver changes. This avoids dependencies
between the two branches. Outside of this main pull request, there are
two topical branches coming as well.
This pull request contains:
- A set of fixes, and a conversion to blk-mq, of nbd. From Josef.
- Set of fixes and updates for lightnvm from Matias, Simon, and Arnd.
Followup dependency fix from Geert.
- General fixes from Bart, Baoyou, Guoqing, and Linus W.
- CFQ async write starvation fix from Glauber.
- Add supprot for delayed kick of the requeue list, from Mike.
- Pull out the scalable bitmap code from blk-mq-tag.c and make it
generally available under the name of sbitmap. Only blk-mq-tag uses it
for now, but the blk-mq scheduling bits will use it as well. From Omar.
- bdev thaw error progagation from Pierre.
- Improve the blk polling statistics, and allow the user to clear them.
From Stephen.
- Set of minor cleanups from Christoph in block/blk-mq.
- Set of cleanups and optimizations from me for block/blk-mq.
- Various nvme/nvmet/nvmeof fixes from the various folks.
Please pull!
