To add - I did try and apply this patch to 4.10.1 but most hunks
failed to apply, and the resultant output didn't work. Quite possibly
not an insurmountable problem but certainly not as simple as apply
diff and away I go.. (I had been most excited by the concept of
knowing which files/ACLs actually caused sysvolreset to choke)
