Subject: [PATCH 0/1] fs: Support compiling out the pivot_root syscall
Date: Sat, 25 Feb 2017 19:54:46 -0500	[thread overview]
Message-ID: <cover.1488054758.git.bosrsf04@gmail.com> (raw)
In-Reply-To: <20170225160648.GQ29622@ZenIV.linux.org.uk>

This patch will allow for the pivot_root syscall to be made
optional. Based on feedback, this patch uses an ifdef in the
source rather than conditional compilation in the Makefile.

The pivot_root syscall is not needed on systems that do not use
any intermediate filesystem. Allowing for pivot_root to be
ommitted from the kernel will aid in the tinification efforts.
