From 413064a95645ab569c2adae4e422cc6aefdf8304 Mon Sep 17 00:00:00 2001 From: Sander Vrijders Date: Wed, 25 Apr 2018 15:46:43 +0200 Subject: lib: Fix bad unlinking of old shared memory A previous commit tried to stat the shared memory file in case it was already there, but stat does not seem to work for shared memory files. This simply omits the O_EXCL attribute upon creation of the shared memory file, since pids are unique anyway.
