From 42f15d77df8a7e8a2feb15041d5d30710ee7f951 Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Fri, 6 Feb 2009 11:35:57 -0500 Subject: Btrfs: Make sure dir is non-null before doing S_ISGID checks The S_ISGID check in btrfs_new_inode caused an oops during subvol creation because sometimes the dir is null.
