I really wish people (and redhat) just stop using XFS altogether. I have seen it break multiple times with two different scenarios:
1) Backup system with external media (usb3) on XFS. The USB link goes down, the kernel panics inside some XFS code. Hard reset needed.
2) Production system with <1M files being actively read by apache http. Hot updating this folder via rsync randomly panics the system.
After a couple of times you just migrate to something sane, like ext4, and everything works flawlessly.
