Subject: [PATCH 2/2] perf beauty: Move uapi/linux/mount.h copy out of the directory used to build perf
Date: Tue, 12 Mar 2024 17:51:12 -0300
Message-ID: <20240312205112.688776-3-acme@kernel.org>
In-Reply-To: <20240312205112.688776-1-acme@kernel.org>

From: Arnaldo Carvalho de Melo <acme@redhat.com>

It is mostly used only to generate string tables, not to build perf, so
move it to the tools/perf/trace/beauty/include/ hierarchy, that is used
just for scrapping.

This is a something that should've have happened, as happened with the
linux/socket.h scrapper, do it now as Ian suggested while doing an
audit/refactor session in the headers used by perf.

No other tools/ living code uses it, just <linux/mount.h> coming from
either 'make install_headers' or from the system /usr/include/
directory.
