Subject: make-good_sigevent-non-static fix
From: Sébastien Dugué <sebastien.dugue@xxxxxxxx>
Could you replace make-good_sigevent-non-static.patch with this
patch, as it fixes some problems reported by Oleg Nesterov.
Oleg, chime in if you still see something I missed.
Hopefully I will have gotten it right this time.
Sorry for the hassle.
Sébastien.
Make good_sigevent() non-static and rename it
Move good_sigevent() from posix-timers.c to signal.c where it belongs,
clean it up, rename it to sigevent_find_task() to better describe what the
function does and make it non-static so that it can be used by other
subsystems.
