From 6c2d8f8d307033a7cdfee3f4cb9dc4679ab69513 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Thu, 22 Sep 2016 13:39:07 -0400 Subject: NFSv4: nfs_inode_find_state_and_recover() should check all stateids Modify the helper nfs_inode_find_state_and_recover() so that it can check all open/lock/delegation state trackers on that inode for whether or not they need are affected by a revoked stateid error.
