From: Paulo Alcantara <pc@cjr.nz> stable inclusion from linux-4.19.181 commit 3cbf408b5ae6d384fffc9dabe4f5cad2f3906d89 -------------------------------- commit 14302ee3301b3a77b331cc14efb95bf7184c73cc upstream. In cifs_statfs(), if server->ops->queryfs is not NULL, then we should use its return value rather than always returning 0. Instead, use rc variable as it is properly set to 0 in case there is no server->ops->queryfs.
