Hi, Prarit
I noticed that you don't mention another question I asked in last mail.
"It looks like cpu_online_mask will be updated until cpu_disable_common
is called, but your check_vectors is called before that."
native_cpu_disable
cpu_disable_common
remove_cpu_from_maps
/*
* until here, cpu_online_mask/cpu_online_bits
* is cleared
*/
set_cpu_online(cpu, false);
Something I missed?
