Merge tag 'for-linus-20180727' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe: "Bigger than usual at this time, mostly due to the O_DIRECT corruption issue and the fact that I was on vacation last week. This contains: - NVMe pull request with two fixes for the FC code, and two target fixes (Christoph) - a DIF bio reset iteration fix (Greg Edwards) - two nbd reply and requeue fixes (Josef) - SCSI timeout fixup (Keith) - a small series that fixes an issue with bio_iov_iter_get_pages(), which ended up causing corruption for larger sized O_DIRECT writes that ended up racing with buffered writes (Martin Wilck)" * tag 'for-linus-20180727' of git://git.kernel.dk/linux-block: block: reset bi_iter.bi_done after splitting bio block: bio_iov_iter_get_pages: pin more pages for multi-segment IOs blkdev: __blkdev_direct_IO_simple: fix leak in error case block: bio_iov_iter_get_pages: fix size of last iovec nvmet: only check for filebacking on -ENOTBLK nvmet: fixup crash on NULL device path scsi: set timed out out mq requests to complete blk-mq: export setting request completion state nvme: if_ready checks to fail io to deleting controller nvmet-fc: fix target sgl list on large transfers nbd: handle unexpected replies better nbd: don't requeue the same request twice.
