Subject: [PATCH 3/3] perf trace powerpc: Use generated syscall table
Date: Mon, 29 Jan 2018 14:04:17 +0530 [thread overview]
Message-ID: <20180129083417.31240-4-ravi.bangoria@linux.vnet.ibm.com> (raw)
In-Reply-To: <20180129083417.31240-1-ravi.bangoria@linux.vnet.ibm.com>
This should speed up accessing new system calls introduced with the
kernel rather than waiting for libaudit updates to include them.
It also enables users to specify wildcards, for example, perf trace -e
'open*', just like was already possible on x86 and s390.
