[PATCH v2 2/5] vfs: add an errseq_t pointer arg to sync_filesystem and __sync_filesystem

[Jeff Layton <jlayton@kernel.org>]

From: Jeff Layton <jlayton@redhat.com>

Allow sync_filesystem and __sync_filesystem to take an errseq_t pointer
for the purposes of error reporting. For now, everything passes in NULL
and the field is ignored, but a later patch will change that.

Signed-off-by: Jeff Layton <jlayton@redhat.com>
