Hi, This patchset has been staged in linux-next for the 6.4 merge window. As detailed in the "Testing" section of the header for patch 5: these changes have been extensively tested in terms of dm-thin (and dm-cache as much as device-mapper-test-suite provides). But further testing from other more exotic DM bufio consumers is needed (e.g. dm-verity and dm-integrity developers/consumers who are Cc'd). Please use whatever tests you have to put pressure on bufio. In particular: focused testing of bufio's shrinker, verify DM_BUFIO_CLIENT_NO_SLEEP (via dm-verity's tasklets), etc. There is still time to add fixes for 6.4 should any issues turn up. All review is welcome (I'll rebase to include Reviewed-by or Acked-by tags). Also, positive reports in the form of Tested-by replies (to patch 5) are also welcome!
