In xfs/318 and xfs/325 we inject errors on extent freeing then delete some files to see if we can make the filesystem go offline. However, with the advent of deferred inode inactivation, sync won't guarantee that unlinked inodes removal is actually pushed to disk since the "inode needs to be deallocated" state is persisted to disk. Freeze achieves this, however, so inject a freeze/thaw cycle to make sure we hit the injected error. Signed-off-by: Darrick J.
