Subject: [PATCH v2 5/9] sysctl: make ngroups_max const
Date: Tue, 23 Nov 2021 12:23:43 -0800	[thread overview]
Message-ID: <20211123202347.818157-6-mcgrof@kernel.org> (raw)
In-Reply-To: <20211123202347.818157-1-mcgrof@kernel.org>

From: Stephen Kitt <steve@sk2.org>

ngroups_max is a read-only sysctl entry, reflecting NGROUPS_MAX. Make
it const, in the same way as cap_last_cap.
