Subject: [PATCH 12/35] perf utils: Move is_directory() to path.h
Date: Thu, 28 Dec 2017 11:30:04 -0300 [thread overview]
Message-ID: <20171228143027.30547-13-acme@kernel.org> (raw)
In-Reply-To: <20171228143027.30547-1-acme@kernel.org>
From: Jiri Olsa <jolsa@kernel.org>
So that it can be used more widely, like in the next patch, when it will
be used to fix a bug in 'perf test' handling of dirent.d_type ==
DT_UNKNOWN.
