Subject: [PATCH] NFS: Do not report EINTR/ERESTARTSYS as mapping errors
Git-commit: cea9ba7239dcc84175041174304c6cdeae3226e5
Patch-mainline: v5.19
References: git-fixes

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")
