Subject: [dpdk-dev] [PATCH v2 2/3] kernel/linux: reduce unneeded indents in meson build file
Date: Fri, 17 May 2019 14:45:28 +0100	[thread overview]
Message-ID: <20190517134529.18160-3-bruce.richardson@intel.com> (raw)
In-Reply-To: <20190517134529.18160-1-bruce.richardson@intel.com>

Since meson 0.46, meson has supported the subdir_done() function, which
allows us to abort processing of a file early. Using this we can reduce the
indentation in our files by eliminating unnecessary else blocks.
