Subject: [PATCH 14/17] drbd: rename "usermode_helper" to "drbd_usermode_helper"
Date: Thu, 24 Aug 2017 23:23:11 +0200 [thread overview]
Message-ID: <1503609794-13233-15-git-send-email-philipp.reisner@linbit.com> (raw)
In-Reply-To: <1503609794-13233-1-git-send-email-philipp.reisner@linbit.com>
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Nothing like having a very generic global variable in a tiny driver
subsystem to make a mess of the global namespace...
Note, there are many other "generic" named global variables in the drbd
subsystem, someone should fix those up one day before they hit a linking
error.
