BTW jffs2_garbage_collect_thread() is a horrible abomination :-)
Its use of SIGSTOP and SIGHUP is *totally* gratuitous & unwarranted.
It does use SIGKILL, but simply as a stop-notification from umount
of the corresponding jffs2 partition.

I think all the signal handling there can be removed; then it needs
to undergo conversion to kthread (it uses horrible locks and
completions to handle its exit) -- I'll put it in my endless
kernel-cleanups-todo-list ...
