Subject: [PATCH 16/35] perf beauty msg_flags: Add missing %s lost when adding prefix suppression logic
Date: Thu, 7 Mar 2019 14:44:14 -0300 [thread overview]
Message-ID: <20190307174433.28819-17-acme@kernel.org> (raw)
In-Reply-To: <20190307174433.28819-1-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
When the prefix suppresion/enabling logic was added, I forgot to add an
extra %, which ended up chopping off the strings:
Before:
# perf trace -e *mmsg --map-dump syscalls
[299] = 1,
[307] = 1,
DNS Res~ver #3/14587 sendmmsg(106<socket:[3462393]>, 0x7f252b0fcaf0, 2, MSG_) = 2
chronyd/1053 recvmmsg(4, 0x558542ca5740, 4, MSG_, NULL) = 1
DNS Res~ver #2/14445 sendmmsg(106<socket:[3461475]>, 0x7f252ab09af0, 2, MSG_) = 2
DNS Res~ver #2/14444 sendmmsg(146<socket:[3457863]>, 0x7f2521a7aaf0, 2, MSG_) = 2
DNS Res~ver #2/14445 sendmmsg(106<socket:[3461475]>, 0x7f252ab09af0, 2, MSG_) = 2
DNS Res~ver #3/14587 sendmmsg(148<socket:[3460636]>, 0x7f252b0fcaf0, 2, MSG_) = 2
DNS Res~ver #2/14444 sendmmsg(146<socket:[3457863]>, 0x7f2521a7aaf0, 2, MSG_) = 2
^C#
After:
# perf trace -e *mmsg --map-dump syscalls
[299] = 1,
[307] = 1,
NetworkManager/17467 sendmmsg(22<socket:[3466493]>, 0x7f28927f9bb0, 2, MSG_NOSIGNAL) = 2
pool/17478 sendmmsg(10<socket:[3466523]>, 0x7f2769f95e90, 2, MSG_NOSIGNAL) = 2
DNS Res~ver #3/14587 sendmmsg(121<socket:[3466132]>, 0x7f252b0fcaf0, 2, MSG_NOSIGNAL) = 2
chronyd/1053 recvmmsg(4, 0x558542ca5740, 4, MSG_DONTWAIT, NULL) = 1
Socket Thread/17433 sendmmsg(121<socket:[3460903]>, 0x7f252668baf0, 2, MSG_NOSIGNAL) = 2
