Hello,

We are seeing a kernel panic triggered with LTP and xfstests against a recent commit for mainline,
wanted to share in case it's not already known.

Kernel repo: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
  Commit: 61a09258f2e5 - Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma

We have also seen it with 2c523b344dfa and 378fee2e6b12 commits as well.

LTP: https://cki-artifacts.s3.us-east-2.amazonaws.com/datawarehouse/2020/03/08/477469/x86_64_1_console.log
xfstests: https://cki-artifacts.s3.us-east-2.amazonaws.com/datawarehouse/2020/03/08/477469/x86_64_4_console.log
