Merge tag 'for-linus-20181026' of git://git.kernel.dk/linux-block
Pull more block layer updates from Jens Axboe:
- Set of patches improving support for zoned devices. This was ready
before the merge window, but I was late in picking it up and hence it
missed the original pull request (Damien, Christoph)
- libata no link power management quirk addition for a Samsung drive
(Diego Viola)
- Fix for a performance regression in BFQ that went into this merge
window (Federico Motta)
- Fix for a missing dma mask setting return value check (Gustavo)
- Typo in the gdrom queue failure case (me)
- NULL pointer deref fix for xen-blkfront (Vasilis Liaskovitis)
- Fixing the get_rq trace point placement in blk-mq (Xiaoguang Wang)
- Removal of a set-but-not-read variable in cdrom (zhong jiang)
