Subject: [PATCH v2] gdb: lx-symbols: store the abspath()
Date:   Thu, 17 Dec 2020 09:17:47 +0100
Message-Id: <20201217091747.bf4332cf2b35.I10ebbdb7e9b80ab1a5cddebf53d073be8232d656@changeid>

From: Johannes Berg <johannes.berg@intel.com>

If we store the relative path, the user might later cd to a
different directory, and that would break the automatic symbol
resolving that happens when a module is loaded into the target
kernel. Fix this by storing the abspath() of each path given,
just like we already do for the cwd (os.getcwd() is absolute.)
