Yes, these options were deprecated for a long time (10 years) and now they are removed since nobody complained. The reasoning is in commit f70486055ee ("ext4: try to deprecate noacl and noxattr_user mount options"): No other file system allows ACL's and extended attributes to be enabled or disabled via a mount option. So let's try to deprecate these options from ext4. - And it makes sense to me. It looks a bit strange and dangerous to disable (part of) permission checks for the files. What usecase did you have for it? Honza -- Jan Kara <jack@xxxxxxxx> SUSE Labs, CR
