From 54640d238760a1a54dfebe039b49682522100186 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Mon, 18 Sep 2017 22:51:14 -0500 Subject: fcntl: Don't set si_code to SI_SIGIO when sig == SIGPOLL When fixing things to avoid ambiguous cases I had a thinko and included SIGPOLL/SIGIO in with all of the other signals that have signal specific si_codes. Which is completely wrong. Fix that. Reported-by: Vince Weaver Signed-off-by: "Eric W.
