Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe:
- an NVMe fix from Gabriel, fixing a suspend/resume issue on some
setups
- addition of a few missing entries in the block queue sysfs
documentation, from Joe
- a fix for a sparse shadow warning for the bvec iterator, from
Johannes
- a writeback deadlock involving raid issuing barriers, and not
flushing the plug when we wakeup the flusher threads. From
Konstantin
- a set of patches for the NVMe target/loop/rdma code, from Roland and
Sagi
