From df66e75395c839c3a373bae897dbb1248f741b45 Mon Sep 17 00:00:00 2001 From: Harshula Jayasuriya Date: Tue, 23 Jul 2013 14:05:14 +1000 Subject: [PATCH] nfsd: nfs4_file_get_access: need to be more careful with O_RDWR If fi_fds = {non-NULL, NULL, non-NULL} and oflag = O_WRONLY the WARN_ON_ONCE(!(fp->fi_fds[oflag] || fp->fi_fds[O_RDWR])) doesn't trigger when it should.
