[PATCH 5.15 497/667] NFS: Dont report errors from nfs_pageio_complete() more than once

From: Greg Kroah-Hartman
Date: Tue Jun 07 2022 - 15:53:32 EST


From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>

[ Upstream commit c5e483b77cc2edb318da152abe07e33006b975fd ]

Since errors from nfs_pageio_complete() are already being reported
through nfs_async_write_error(), we should not be returning them to the
callers of do_writepages() as well. They will end up being reported
through the generic mechanism instead.

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