Subject: [PATCH 7/8] bootstrap_read_devfs(): Remove all partitions upon function completion
Date: Sun, 3 May 2015 13:13:18 -0700 [thread overview]
Message-ID: <1430683999-5910-7-git-send-email-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <1430683999-5910-1-git-send-email-andrew.smirnov@gmail.com>
Bootstrap_read_devfs does not remove the devices it creates during the
course of its execution which might be considered as a resource
leak. Remedy that by adding the code to remove those devices upon
function completion.
