From 48380368dec14859723b9e3fbd43e042638d9a76 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Wed, 29 Mar 2023 12:14:42 +0200 Subject: Change DEFINE_SEMAPHORE() to take a number argument Fundamentally semaphores are a counted primitive, but DEFINE_SEMAPHORE() does not expose this and explicitly creates a binary semaphore. Change DEFINE_SEMAPHORE() to take a number argument and use that in the few places that open-coded it using __SEMAPHORE_INITIALIZER().
