From 0c95c025a02e477b2d112350e1c78bb0cc994c51 Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Wed, 1 Feb 2023 14:14:55 +0100 Subject: [PATCH] fs: drop unused posix acl handlers Remove struct posix_acl_{access,default}_handler for all filesystems that don't depend on the xattr handler in their inode->i_op->listxattr() method in any way. There's nothing more to do than to simply remove the handler. It's been effectively unused ever since we introduced the new posix acl api.
