What

In Rook(*1)/Ceph community, some users encountered hang_task in XFS. Although Neco hasn't hit this problem, it's better to fix it for Rook/Ceph community. In addition, we might hit it later.

This problem doesn't come from Rook and happens due to kernel. In addition, the detail of this problem is described in Rook/Ceph's common issues. So I consider this Rook's issue can be closed.
