Subject: [PATCH 5.17 581/772] NFS: fsync() should report filesystem errors over EINTR/ERESTARTSYS
From: Trond Myklebust <trond.myklebust@...merspace.com>
[ Upstream commit 9641d9bc9b75f11f70646f5c6ee9f5f519a1012e ]
If the commit to disk is interrupted, we should still first check for
filesystem errors so that we can report them in preference to the error
due to the signal.
Fixes: 2197e9b06c22 ("NFS: Fix up fsync() when the server rebooted")
