      Linus Torvalds 提交于
      Pull device mapper fixes from Mike Snitzer:
      
       - revert a request-based DM core change that caused IO latency to
         increase and adversely impact both throughput and system load
      
       - fix for a use after free bug in DM core's device cleanup
      
       - a couple DM btree removal fixes (used by dm-thinp)
      
       - a DM thinp fix for order-5 allocation failure
      
       - a DM thinp fix to not degrade to read-only metadata mode when in
         out-of-data-space mode for longer than the 'no_space_timeout'
      
       - fix a long-standing oversight in both dm-thinp and dm-cache by now
         exporting 'needs_check' in status if it was set in metadata
      
       - fix an embarrassing dm-cache busy-loop that caused worker threads to
         eat cpu even if no IO was actively being issued to the cache device

      blk-mq: set default timeout as 30 seconds · e56f698b
      Ming Lei 提交于
      It is reasonable to set default timeout of request as 30 seconds instead of
      30000 ticks, which may be 300 seconds if HZ is 100, for example, some arm64
      based systems may choose 100 HZ.

      dm thin: stay in out-of-data-space mode once no_space_timeout expires · bcc696fa
      Mike Snitzer 提交于
      This fixes an issue where running out of data space would cause the
      thin-pool's metadata to become read-only.  There was no reason to make
      metadata read-only -- calling set_pool_mode() with PM_READ_ONLY was a
      misguided way to error all queued and future write IOs.  We can
      accomplish the same by degrading from PM_OUT_OF_DATA_SPACE to
      PM_OUT_OF_DATA_SPACE with error_if_no_space enabled.
      
      Otherwise, the use of PM_READ_ONLY could cause a race where commit() was
      started before the PM_READ_ONLY transition but dm_pool_commit_metadata()
      would go on to fail because the block manager had transitioned to
      read-only.  The return of -EPERM from dm_pool_commit_metadata(), due to
      attempting to commit while in read-only mode, caused the thin-pool to
      set 'needs_check' because a metadata_operation_failed().  This needless
      cascade of failures makes life for users more difficult than needed.
