| |
Hi Linus,
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.
Please pull!
