[PATCH bpf-next v1 01/22] locking: Move MCS struct definition to public header
From: Kumar Kartikeya Dwivedi
Date: Tue Jan 07 2025 - 09:00:26 EST
Move the definition of the struct mcs_spinlock from the private
mcs_spinlock.h header in kernel/locking to the mcs_spinlock.h
asm-generic header, since we will need to reference it from the
qspinlock.h header in subsequent commits.
