Subject: [PATCH 05/11] moduleparam: Rename .get field to .get_str
Date: Thu, 21 May 2026 06:33:18 -0700	[thread overview]
Message-ID: <20260521133326.2465264-5-kees@kernel.org> (raw)
In-Reply-To: <20260521133315.work.845-kees@kernel.org>

Now that every kernel_param_ops initializer in the tree goes through
DEFINE_KERNEL_PARAM_OPS, no source file outside kernel/params.c and
include/linux/moduleparam.h references the .get field by name. Take
advantage of that to rename the field to .get_str.

The bare .get name is now free for the next commit, which adds it
back as a struct seq_buf *-based callback.
