autofs-5.1.4 - make umount_ent() recognise forced umount
From: Ian Kent <raven@themaw.net>
When doing a forced shutdown umount_ent() tries a normal expire
first resulting in a fair amount of unnecessary log noise.
Change umount_ent() to do a forced expire when a forced shutdown
has been requested to avoid the log noise.

autofs-5.1.8 - fix handling of incorrect return from umount_ent()
From: Ian Kent <raven@themaw.net>
Commit 0210535df4b ("autofs-5.1.0 - gaurd against incorrect umount
return") guards against umount_ent() returning a fail when the mount
has actually been umounted.
But we also see umount_ent() return success when in fact the mount has
not been umounted leading to incorrect handling of automounts.
So checking the return of umount_ent() isn't always giving the correct
result in more than just one case, consequently we should ignore the
result from the spawned umount(8) and check if the mount has in fact
been umounted.

autofs-5.1.8 - remove nonstrict parameter from tree_mapent_umount_offsets()
From: Ian Kent <raven@themaw.net>
The nonstrict parameter of tree_mapent_umount_offsets() ins't useful
because if a real mount at the base of a sub-tree fails to umount all
we can do is re-instate the offset mounts under it which must succeed
for the mount tree to remain useful.
