Short answer:
http://lxr.linux.no/ident?v=2.5.56&i=jffs2_garbage_collect_pass

Long answer:

jffs2_garbage_collect_pass is called from the GC thread, but also from
all processes writing to flash. The GC thread basically runs
permanently on idle systems and a little on busy ones. Sending SIGHUP
to it triggers exactly one run of jffs2_garbage_collect_pass, so a
single signal will barely be noticed. Not at all for idle systems.
