Subject: [PATCH 1/4] arch: um: remove sig_info[SIGALRM]
Date: Fri, 23 Aug 2019 12:44:26 +0200 [thread overview]
Message-ID: <20190823104429.11047-1-johannes@sipsolutions.net> (raw)
From: Johannes Berg <johannes.berg@intel.com>
This entry is misleading, the actual signal handler is
another one that never uses sig_info.
Also remove the SIGALRM if inside sig_handler() for the
same reason.
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
