Subject: [PATCH 5.15 493/667] NFS: Do not report EINTR/ERESTARTSYS as mapping errors

From: Trond Myklebust <trond.myklebust@...merspace.com>

[ Upstream commit cea9ba7239dcc84175041174304c6cdeae3226e5 ]

If the attempt to flush data was interrupted due to a local signal, then
just requeue the writes back for I/O.

Fixes: 6fbda89b257f ("NFS: Replace custom error reporting mechanism with generic one")
