Subject: [dpdk-dev] [PATCH v7 11/11] devtools: prevent new instances of rte_panic and rte_exit
Date: Wed, 25 Apr 2018 01:16:53 +0300	[thread overview]
Message-ID: <1524608213-2080-12-git-send-email-arnon@qwilt.com> (raw)
In-Reply-To: <1524608213-2080-1-git-send-email-arnon@qwilt.com>

This patch adds a new function that is called
per every checked patch,
and alerts for new instances of rte_panic/rte_exit.
The check excludes comments, and alerts in the case
of a positive balance between additions and removals.
