Subject: [PATCH v2 1/7] pNFS: Mark layout for return if return-on-close was not sent
Date: Thu, 7 Jan 2021 00:31:24 -0500 [thread overview]
Message-ID: <20210107053130.20341-1-trondmy@kernel.org> (raw)
From: Trond Myklebust <trond.myklebust@hammerspace.com>
If the layout return-on-close failed because the layoutreturn was never
sent, then we should mark the layout for return again.
Fixes: 9c47b18cf722 ("pNFS: Ensure we do clear the return-on-close layout stateid on fatal errors")
Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
