Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe: "This contains a set of fixes for xen-blkback by way of Konrad, and a performance regression fix for blk-mq for shared tags. The latter could account for as much as a 50x reduction in performance, with the test case from the user with 500 name spaces. A more realistic setup on my end with 32 drives showed a 3.5x drop. The fix has been thoroughly tested before being committed" * 'for-linus' of git://git.kernel.dk/linux-block: blk-mq: fix performance regression with shared tags xen-blkback: don't leak stack data via response ring xen/blkback: don't use xen_blkif_get() in xen-blkback kthread xen/blkback: don't free be structure too early xen/blkback: fix disconnect while I/Os in flight
