Subject: [PATCH 1/2] locking: don't check for __LINUX_SPINLOCK_TYPES_H on -RT
|
|
archs
|
|
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.1-rt3.tar.xz
|
|
|
|
Upstream uses arch_spinlock_t within spinlock_t and requests that
|
|
spinlock_types.h header file is included first.
|
|
On -RT we have the rt_mutex with its raw_lock wait_lock which needs
|
|
architectures' spinlock_types.h header file for its definition. However
|
|
we need rt_mutex first because it is used to build the spinlock_t so
|
|
that check does not work for us.
|
|
Therefore I am dropping that check.
|
|
