Subject: [PATCH v3 0/3] Fix double allocation in swiotlb_alloc()
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
