Function fs_node_copy_up 

pub fn fs_node_copy_up<R>(
    current_task: &CurrentTask,
    fs_node: &FsNode,
    do_copy_up: impl FnOnce() -> R,
) -> R

Sets the security context of CurrentTask to be appropriate for a copy up operation on fs_node, then call do_copy_up. The task’s security context will be reset before returning.

Corresponds to the security_inode_copy_up() LSM hook.
