2 A description of what robust futexes are10 what are robust futexes? To answer that, we first need to understand11 what futexes are: normal futexes are special types of locks that in the28 method makes futexes very lightweight and scalable.45 (and in most cases there is none, futexes being fast lightweight locks)56 robust futexes attached to this area'. This approach requires 3 new75 because the kernel has no knowledge about how many robust futexes there82 robust futexes impractical for any type of generic Linux distribution.86 New approach to robust futexes97 the cost of robust futexes is just a simple current->robust_list != NULL[all …]
