Subject: [PATCH bpf-next v1 01/22] locking: Move MCS struct definition to public header
Date: Tue,  7 Jan 2025 05:59:43 -0800	[thread overview]
Message-ID: <20250107140004.2732830-2-memxor@gmail.com> (raw)
In-Reply-To: <20250107140004.2732830-1-memxor@gmail.com>

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.
