Subject: [lustre-devel] [PATCH 32/41] lustre: mark strings in char arrays as const
Date: Sun,  4 Apr 2021 20:51:01 -0400	[thread overview]
Message-ID: <1617583870-32029-33-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1617583870-32029-1-git-send-email-jsimmons@infradead.org>

From: Mr NeilBrown <neilb@suse.de>

Most array of strings are marked 'const', but the strings within the
arrays often aren't.
This patch mark all strings in const arrays of strings as const.
This allows them to be placed in read-only memory.
