From 32bf1deae15b67839a2f0cb233254125be73fc78 Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Tue, 20 May 2014 07:41:43 +1000 Subject: [PATCH] xfs: keep sb_bad_features2 the same a sb_features2 Whenever we update sb_features2, we need to update sb_bad_features2 so that they remain identical on disk. This prevents future mounts or userspace utilities from getting confused over which features the filesystem supports.
