Subject: [PATCH 16/16] perf tools: Sync copy of syscall_64.tbl with the kernel
Date: Mon, 4 Jul 2016 21:38:35 -0300 [thread overview]
Message-ID: <1467679115-20496-17-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1467679115-20496-1-git-send-email-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Noticed by the build system, that emitted this warning:
Warning: x86_64's syscall_64.tbl differs from kernel
This was due to the wiring up of the recently added preadv2 & pwritev2
syscalls to the compat code, which hadn't been done by the patch
introducing those syscalls: 4babf2c5efb7 ("x86: wire up preadv2 and
pwritev2").
The patch doing the compat wiring was:
482dd2ef1244 ("x86/syscalls: Wire up compat readv2/writev2 syscalls")
This just silences the perf build warning, as compat syscalls still
can't be supported in 'perf trace´ due to limitations in the
raw_syscalls:sys_{enter,exit} tracepoints it relies on.
