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. COPYRIGHT Kernel Hackers Manual 2.6. November 2013 LIST_EMPTY_CAREFUL(9)[top]
