[PATCH openEuler-22.03-LTS-SP1 0/5] nfs: Ensure that the NFS client returns a correct writeback error code

Backport community mainline patch to make close and writeback return correct return values:

Scott Mayhew (2): nfs: nfs_file_write() should check for writeback errors nfs: ensure correct writeback errors are returned on close()

Trond Myklebust (2): NFS: Use of mapping_set_error() results in spurious errors NFS: Don't report ENOSPC write errors twice

HULK solution to avoid residual error codes:

Wang Zhaolong (1): nfs: Ensure write and flush consume writeback errors
