[AppArmor 04/41] Pass struct file down to remove_suid and children

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Pass struct path to remove_suid and should_remove_suid instead of
only the dentry. Required by a later patch that adds a struct
vfsmount parameter to notify_change().
