Subject: [PATCH 0/4] xfs: ioend batching log reservation deadlock
Date: Mon, 5 Apr 2021 10:58:59 -0400 [thread overview]
Message-ID: <20210405145903.629152-1-bfoster@redhat.com> (raw)
Hi all,
This series addresses the ioend completion batching log res deadlock
vector by removing the preallocated transaction from append ioends.
Instead, we continue to process append ioend completions via the
workqueue, but let the wq task allocate the transaction similar to other
ioend types.
Patch 1 makes the functional change and the remaining patches are
followon cleanups. Technically this could all be squashed down to a
single patch, if desired. Thoughts, reviews, flames appreciated.
Brian
