Subject: [PATCH v4 0/1] vfs-6.19.iomap commit 51311f045375 fixup
Date: Fri, 31 Oct 2025 14:13:08 -0700 [thread overview]
Message-ID: <20251031211309.1774819-1-joannelkoong@gmail.com> (raw)
This fixes the race that was reported by Brian in [1]. This fix was locally
verified by running the repro (running generic/051 in a loop on an xfs
filesystem with 1k block size).
Thanks,
Joanne
