[ovs-dev] [PATCH v2] lib/util.c: Optimise bitwise_rscan.

[William Tu]

Hi Han Zhou,

Just curious and not related to the bitwise_rscan().
Do you get a chance to know what this kernel symbol is?

you can try "cat /proc/kallsyms" and see where it locates.

btw, I remembered you have tried jemalloc. Does jemalloc have lower
__int_malloc/free number?
