LIST_EMPTY_CAREFUL(9)		  Data Types		 LIST_EMPTY_CAREFUL(9)

NAME
       list_empty_careful - tests whether a list is empty and not being
       modified

SYNOPSIS
       int list_empty_careful(const struct list_head * head);

ARGUMENTS
       head
	   the list to test

DESCRIPTION
       tests whether a list is empty _and_ checks that no other CPU might be
       in the process of modifying either member (next or prev)

NOTE
       using list_empty_careful without synchronization can only be safe if
       the only activity that can happen to the list entry is list_del_init.
       Eg. it cannot be used if another CPU could re-list_add it.
