how to init rwlock_t

Question

I am writing a linux kernel module, and I can't find a way to initialise my read-write lock. I prefer a static init.

When I try using RW_LOCK_UNLOCKED, the compiler tells me that it is not defined.

rwlock_t lock = RW_LOCK_UNLOCKED;

Answer 1

Use the Source, Luke:

DEFINE_RWLOCK(lock);
