Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block layer fixes from Jens Axboe: "A small collection of fixes that should go in before -rc1. The pull request contains: - A two patch fix for a regression with block enabled tagging caused by a commit in the initial pull request. One patch is from Martin and ensures that SCSI doesn't truncate 64-bit block flags, the other one is from me and prevents us from double using struct request queuelist for both completion and busy tags. This caused anything from a boot crash for some, to crashes under load. - A blk-mq fix for a potential soft stall when hot unplugging CPUs with busy IO. - percpu_counter fix is listed in here, that caused a suspend issue with virtio-blk due to percpu counters having an inconsistent state during CPU removal. Andrew sent this in separately a few days ago, but it's here. JFYI. - A few fixes for block integrity from Martin. - A ratelimit fix for loop from Mike Galbraith, to avoid spewing too much in error cases" * 'for-linus' of git://git.kernel.dk/linux-block: block: fix regression with block enabled tagging scsi: Make sure cmd_flags are 64-bit block: Ensure we only enable integrity metadata for reads and writes block: Fix integrity verification block: Fix for_each_bvec() drivers/block/loop.c: ratelimit error messages blk-mq: fix potential stall during CPU unplug with IO pending percpu_counter: fix bad counter state during suspend
