From 0653f1d809d0cc13f84facb9d2d82d984ac4d0ac Mon Sep 17 00:00:00 2001
From: Richard Purdie <richard.purdie@linuxfoundation.org>
Date: Tue, 9 Mar 2021 15:25:16 +0000
Subject: [PATCH 3/3] syscalls/swapon/swapoff: Move common library to libs/
There is a race/determinism issue with libswapon currently as depending on
which makefile path builds it, the debug paths may be "../swapon/libswapon.c"
or "libswapon.c". To avoid the determinism issue, move libswapon to libs/
and use it from the shared location.
The header is moved to the common includes directory to match and
the Makefile.inc fragment can be dropped.
