I'll see if I have time to install an fc21 vm or maybe upgrade from source. (Any easy way?) I have setup my xfs rig and ran "./check -g auto" by now. I tried both part_show=1/0 and both look working as expected. (Do I need any special $MKFS_OPTIONS or anything else) I'll probably be giving up soon, and will just wait for more reports. With the patch-1 I sent I am reverting to old behavior so I need a reproducer to try and run with patch-1 and part_show=1 should show the problem and part_show=0 should not.
