Subject: [PATCH 26/29] xfs: move xfs_xattr_handlers to .rodata
Date: Sat, 30 Sep 2023 02:00:30 -0300	[thread overview]
Message-ID: <20230930050033.41174-27-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
xfs_xattr_handlers at runtime.
