3.6.11.6 stable review patch. If anyone has any objections, please let me know. ------------------ From: Jeff Layton [ Upstream commit c2b93e0699723700f886ce17bb65ffd771195a6d ] It's generally not safe to reset the inode ops once they've been set. In the case where the inode was originally thought to be a directory and then later found to be a DFS referral, this can lead to an oops when we try to trigger an inode op on it after changing the ops to the blank referral operations.
