Subject[PATCH 5.10 330/452] NFS: Do not report flush errors in nfs_write_end()
Date
From: Trond Myklebust <trond.myklebust@hammerspace.com>

[ Upstream commit d95b26650e86175e4a97698d89bc1626cd1df0c6 ]

If we do flush cached writebacks in nfs_write_end() due to the imminent
expiration of an RPCSEC_GSS session, then we should defer reporting any
resulting errors until the calls to file_check_and_advance_wb_err() in
nfs_file_write() and nfs_file_fsync().

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