Merge tag 'block-5.11-2021-02-05' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe: "A few small regression fixes: - NVMe pull request from Christoph: - more quirks for buggy devices (Thorsten Leemhuis, Claus Stovgaard) - update the email address for Keith (Keith Busch) - fix an out of bounds access in nvmet-tcp (Sagi Grimberg) - Regression fix for BFQ shallow depth calculations introduced in this merge window (Lin)" * tag 'block-5.11-2021-02-05' of git://git.kernel.dk/linux-block: nvmet-tcp: fix out-of-bounds access when receiving multiple h2cdata PDUs bfq-iosched: Revert "bfq: Fix computation of shallow depth" update the email address for Keith Bush nvme-pci: ignore the subsysem NQN on Phison E16 nvme-pci: avoid the deepest sleep state on Kingston A2000 SSDs
