Subject: [PATCH 20/29] ocfs2: move ocfs2_xattr_handlers and ocfs2_xattr_handler_map to .rodata
Date: Sat, 30 Sep 2023 02:00:24 -0300 [thread overview]
Message-ID: <20230930050033.41174-21-wedsonaf@gmail.com> (raw)
In-Reply-To: <20230930050033.41174-1-wedsonaf@gmail.com>
From: Wedson Almeida Filho <walmeida@microsoft.com>
This makes it harder for accidental or malicious changes to
ocfs2_xattr_handlers or ocfs2_xattr_handler_map at runtime.
