Subject: [PATCH] sysctl: quiet unused variable warning in fs/proc/proc_sysctl.c:init_header()
Date: Thu, 17 Sep 2026 23:23:38 -0700	[thread overview]
Message-ID: <20260918062338.1039303-1-enelsonmoore@gmail.com> (raw)

The init_header() function uses list_for_each_table_entry() without
using the entry argument. This causes a warning when building with W=1.
Since the code is correct, mark the associated variable as
__maybe_unused.
