for arch/arm/kernel/smp.c
static DEFINE_PER_CPU(struct ipi_data, ipi_data) = {
will give a struct with name per_cpu__ipi_data
so I did
- .lock = SPIN_LOCK_UNLOCKED,
+ .lock = __SPIN_LOCK_UNLOCKED(per_cpu__ipi_data.lock),
but this dosen't seem to be the right thing to do..
the DEFINE_PER_CPU macro internally creates an instance of
the type passed with name as "per_cpu__##name"
the prefix should not be assumed i think
.if the DEFINE_PER_CPU changes ,this code will break..
how do we go about it?
thoughts!
plz CMIIW
