Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block layer fixes from Jens Axboe: "A set of fixes for the current series. This contains: - A bunch of fixes for lightnvm, should be the last round for this series. From Matias and Wenwei. - A writeback detach inode fix from Ilya, also marked for stable. - A block (though it says SCSI) fix for an OOPS in SCSI runtime power management. - Module init error path fixes for null_blk from Minfei" * 'for-linus' of git://git.kernel.dk/linux-block: null_blk: Fix error path in module initialization lightnvm: do not compile in debugging by default lightnvm: prevent gennvm module unload on use lightnvm: fix media mgr registration lightnvm: replace req queue with nvmdev for lld lightnvm: comments on constants lightnvm: check mm before use lightnvm: refactor spin_unlock in gennvm_get_blk lightnvm: put blks when luns configure failed lightnvm: use flags in rrpc_get_blk block: detach bdev inode from its wb in __blkdev_put() SCSI: Fix NULL pointer dereference in runtime PM
