Biederman" , Nathan Chancellor , Nicolas Schier Cc: linux-kernel@vger.kernel.org Subject: [RFC PATCH 0/1] sysctl: remove CONFIG_SYSCTL, it just mirrors CONFIG_PROC_SYSCTL Message-ID: Precedence: bulk X-Mailing-List: linux-kernel@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline X-Scanned-By: MIMEDefang 3.0 on 10.30.177.17 Andrew, Eric, et al, To me it is a bit annoying/confusing to see both CONFIG_PROC_SYSCTL and CONFIG_SYSCTL in the source code (they are the same thing), but... Does it make any sense to try to suggest this patch for -mm tree? It is hopefully trivial (generated by 2 perl one-liners) but touches 170 files. So far I don't even CC maintainers, the output of get_maintainer.pl is huge. Alternatively, we could kill CONFIG_PROC_SYSCTL in favour of CONFIG_SYSCTL. This would result in a much smaller patch, but I am not sure if it is "safe" because CONFIG_PROC_SYSCTL is user-visible in that it has a prompt in fs/proc/Kconfig. But perhaps this is fine? (either way we can make a couple more minor cleanups if we kill one of them). Oleg.
