Yes, no problem. I brought my various earlier changes to the front, dropped my changes for removing dm_io refcounting for normal r/w IO (still visible in 'dm-5.19-v1'), and rebased Ming's series (now visible in 'dm-5.19-v2'). Common: https://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git/log/?h=dm-5.19 Old: https://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git/log/?h=dm-5.19-v1 New: https://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git/log/?h=dm-5.19-v2 I'll clean up the 'dm-5.19-v2' series further and likely post to the list on Tuesday. I discussed with Jens and we'll both be rebasing our 5.19 trees to v5.18-rc3. dm will be rebasing on block (I can fix up Ming's patch for bdev_{start,end}_io_acct based on your review and Jens can then pick it up from the first patch in the series I post).
