Subject: [PATCH 25/29] ubifs: move ubifs_xattr_handlers to .rodata
Date: Sat, 30 Sep 2023 02:00:29 -0300	[thread overview]
Message-ID: <20230930050033.41174-26-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
ubifs_xattr_handlers at runtime.
