That's a Fedora bug and Fedora merely built a newer kernel with the
upstream kernel fix.  It's mostly irrelevant to RHEL and Centos.

According to the CentOS kernel changelog

$ rpm -q --changelog kernel-`uname -r`|less # only relevant lines shown
* Mon Mar 03 2014 Jarod Wilson <jarod at redhat.com> [3.10.0-101.el7]
- [fs] btrfs: take ordered root lock when removing ordered operations
inode (Zach Brown) [1051282]

this might have been fixed in 2014, but I don't have access to
1051282.  There are also scores more btrfs patches in the RHEL 7
kernel since 2013.

I also notice that the stack trace for
https://bugs.centos.org/view.php?id=10944 does NOT mention btrfs, so
it's most likely a different bug.
