      UBUNTU: SAUCE: shiftfs: fix dentry revalidation

  regresses various btrfs + shiftfs users. Creating a btrfs subvolume,
  deleting it, and then trying to recreate it will cause EEXIST to be returned.
  It also leaves some files in a half-visible state because they are not 
  Faulty behavior such as this can be reproduced via:

  btrfs subvolume create my-subvol
  btrfs subvolume delete my-subvol

  Fix: We need to revert this patch restoring the old behavior. This will 
  resurface https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872757 which 
I will fix in a follow-up patch on top of this revert. We basically split the 
part that fixes https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872757 
out of the revert.

  Regression Potential: Limited to shiftfs.

  Test Case: Build a kernel with fix applied and run above reproducer.
