Subject: [PATCH 18/19] perf tools: Add machine__module_dso function
Date: Sat, 21 Mar 2015 15:54:37 -0300 [thread overview]
Message-ID: <1426964078-16384-19-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1426964078-16384-1-git-send-email-acme@kernel.org>
From: Jiri Olsa <jolsa@kernel.org>
Separate the dso object addition and update when adding new kernel
module.
Currently we update dso's symtab_type any time we find it in the list,
because we can't distinguish between new and found dso from
__dsos__findnew function.
Adding machine__module_dso that separates finding and adding new dso
objects, so there's no superfluous update of dso.
