From 916ec34d0bafe95b977908acd8b3153c9df6f9d6 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 17 Jun 2016 16:48:28 -0400 Subject: [PATCH] NFS: Fix potential race in nfs_fhget() If we don't set the mode correctly in nfs_init_locked(), then there is potential for a race with a second call to nfs_fhget that will cause inode aliasing.
