Re: [Dle-develop] [PATCH -tip 3/3] Add get_signal tracepoint

[Roland M. <ro...@re...>]

This is orthogonal to the core-dump tracepoint, I don't see why you
call them a unified patch series.

The proper name for this event is "signal delivery".  But since the
proper name for "send_signal" is "signal generation", I suppose "get"
is analogously improper to the existing "send" tracepoint.  ;-)

Especially if you call this "get" rather than "deliver", there is
another place that should invoke this tracepoint (or perhaps a third
one).  sys_rt_sigtimedwait "gets" a signal without delivering it.  In
POSIX terminology this is called "accepting" the signal: the three
things that can happen in the life of a signal are "generate",
"deliver", and "accept".  If you are trying to match up what happened to
a signal generated by kill() or whatnot, then you want to notice both
delivery and acceptance as the complementary event.

(And again I have no clue why this signal stuff should be called
"sched" at all.)
