All of them point to below reason,
list_del corruption. next->prev should be ffff880c1e567000, but was 00450008a948adba
We searched around web and see this is fixed in redhat https://bugzilla.redhat.com/show_bug.cgi?id=1028750
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.
But don't see any fix in Centos. https://bugs.centos.org/view.php?id=10944
According to the CentOS kernel changelog
$ rpm -q --changelog kernel-`uname -r`|less # only relevant lines shown * Mon Mar 03 2014 Jarod Wilson jarod@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.
