Title:
  kernel panics due to incorrect backport

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  This issue results in kernel panics for anyone who uses CephFS.

  After some digging we suspect this patch to be cause of the kernel
  panics:

  https://kernel.ubuntu.com/git/kernel-ppa/mirror/ubuntu-
  bionic.git/commit/?id=eb0ba4bdcf12d9c29b9d3318627ad9ff3aff5471

  
  This patch same patch was applied upstream (4.19) and reverted: 

  https://lkml.org/lkml/2019/10/3/862

  Quoting: "The backport was incorrect and was causing kernel panics. Revert and
  re-apply a correct backport from Jeff Layton."

  
  Also relevant: 

  https://www.mail-archive.com/ceph-users@lists.ceph.com/msg56549.html

  Which basically states this patch should not have been applied to 4.15
  at all (not intended for pre-5.2)

  Would be great if you guys could revert the patch. 
  We are stuck on previous kernel versions until this issue is fixed.
