9fe5c59ff6a1 # Author: Linus Torvalds <torvalds@linux-foundation.org> # Date: Fri Nov 2 11:25:48 2018 -0700 # # Merge tag 'for-linus-20181102' of git://git.kernel.dk/linux-block # # Pull block layer fixes from Jens Axboe: # "The biggest part of this pull request is the revert of the blkcg # cleanup series. It had one fix earlier for a stacked device issue, but # another one was reported. Rather than play whack-a-mole with this, # revert the entire series and try again for the next kernel release. # # Apart from that, only small fixes/changes. # # Summary: # # - Indentation fixup for mtip32xx (Colin Ian King) # # - The blkcg cleanup series revert (Dennis Zhou) # # - Two NVMe fixes. One fixing a regression in the nvme request # initialization in this merge window, causing nvme-fc to not work. # The other is a suspend/resume p2p resource issue (James, Keith) # # - Fix sg discard merge, allowing us to merge in cases where we didn't # before (Jianchao Wang) # # - Call rq_qos_exit() after the queue is frozen, preventing a hang # (Ming) # # - Fix brd queue setup, fixing an oops if we fail setting up all # devices (Ming)" # # * tag 'for-linus-20181102' of git://git.kernel.dk/linux-block: # nvme-pci: fix conflicting p2p resource adds # nvme-fc: fix request private initialization # blkcg: revert blkcg cleanups series # block: brd: associate with queue until adding disk # block: call rq_qos_exit() after queue is frozen # mtip32xx: clean an indentation issue,
