[PATCH 5.15 100/110] nfsd: fix change_info in NFSv4 RENAME replies

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


5.15-stable review patch.  If anyone has any objections, please let me know.


From: Jeff Layton <jlayton@xxxxxxxxxx>

commit fdd2630a7398191e84822612e589062063bd4f3d upstream.

nfsd sends the transposed directory change info in the RENAME reply. The
source directory is in save_fh and the target is in current_fh.
