Subject: [PATCH 0/2] exit: Introduce __WCHILDSIGINFO for waitid
Date: Mon, 14 Feb 2022 13:38:21 -0800	[thread overview]
Message-ID: <20220214213823.3297816-1-keescook@chromium.org> (raw)

Hi,

Okay, here's a working version of this. Is adding 48 bytes into task
struct worth it? Can this be improved, and is the non-signal-exit logic
for __WCHILDSIGINFO sane?

Other thoughts?

-Kees
