Subject: [PATCH v2 13/29] modpost: load KBUILD_EXTRA_SYMBOLS files in order
Date: Mon, 25 May 2020 00:42:19 +0900 [thread overview]
Message-ID: <20200524154235.380482-14-masahiroy@kernel.org> (raw)
In-Reply-To: <20200524154235.380482-1-masahiroy@kernel.org>
Currently, modpost reads extra symbol dump files in the reverse order.
If '-e foo -e bar' is given, modpost reads bar, foo, in this order.
This is probably not a big deal, but there is no good reason to reverse
the order. Read files in the given order.
