Merge tag 'block-5.13-2021-05-07' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe:
- dasd spelling fixes (Bhaskar)
- Limit bio max size on multi-page bvecs to the hardware limit, to
avoid overly large bio's (and hence latencies). Originally queued for
the merge window, but needed a fix and was dropped from the initial
pull (Changheun)
- NVMe pull request (Christoph):
- reset the bdev to ns head when failover (Daniel Wagner)
- remove unsupported command noise (Keith Busch)
- misc passthrough improvements (Kanchan Joshi)
- fix controller ioctl through ns_head (Minwoo Im)
- fix controller timeouts during reset (Tao Chiu)
- rnbd fixes/cleanups (Gioh, Md, Dima)
- Fix iov_iter re-expansion (yangerkun)
