| |
A patchset that adds more this_cpu operations and in particular RMV operations that can be used in various places to avoid address calculations and memory accesses.
Also adds this_cpu_cmpxchg_double() which is a locally atomic version of cmpxchg and uses that to demo how a lockless, preemptless fastpath for memory allocation could work. Works good enough so that I can write this email with that fastpath scheme.
