Subject: [PATCH 49/63] perf trace: Enclose the errno strings with ()
Date: Tue, 18 Dec 2018 19:07:19 -0300 [thread overview]
Message-ID: <20181218220733.15839-50-acme@kernel.org> (raw)
In-Reply-To: <20181218220733.15839-1-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
To match strace, now both emit the same line for calls like:
access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or directory)
