Hi Linus,
Here's a set of block fixes for the current 4.8-rc release. This pull
request contains:
- A fix for a secure erase regression, from Adrian.
- A fix for an mmc use-after-free bug regression, also from Adrian.
- Potential zero pointer deference in bdev freezing, from Andrey.
- A race fix for blk_set_queue_dying() from Bart.
- A set of xen blkfront fixes from Bob Liu.
- Three small fixes for bcache, from Eric and Kent.
- A fix for a potential invalid NVMe state transition, from Gabriel.
- blk-mq CPU offline fix, preventing us from issuing and completing
a request on the wrong queue. From me.
- Revert two previous floppy changes, since they caused a user visibile
regression. A better fix is in the works.
- Ensure that we don't send down bios that have more than 256 elements
in them. Fixes a crash with bcache, for example. From Ming.
- A fix for deferencing an error pointer with cgroup writeback. Fixes
a regression. From Vegard.
Please pull for 4.8-rc4! Thanks.
