Message-ID: <20240205190127.20685-1-will@kernel.org> (raw)

Hi all,

This is version three of the patches I posted recently:

v1: https://lore.kernel.org/r/20240126151956.10014-1-will@kernel.org
v2: https://lore.kernel.org/r/20240131122543.14791-1-will@kernel.org

Thanks to Robin for the comments on the most recent version.

Changes since v2 include:

  - Restore missing 'continue' statement that got accidentally dropped
    while addressing the initial round of review feedback.

  - Reword the commit message in patch #1

  - Add a Fixes: tag to the last patch

Cheers,

Will
