Subject: [PATCH] riscv: qspinlock: Fixup _Q_PENDING_LOOPS definition
Date: Sun, 15 Dec 2024 08:52:52 -0500 [thread overview]
Message-ID: <20241215135252.201983-1-guoren@kernel.org> (raw)
From: Guo Ren <guoren@linux.alibaba.com>
When CONFIG_RISCV_QUEUED_SPINLOCKS=y, the _Q_PENDING_LOOPS
definition is missing. Add the _Q_PENDING_LOOPS definition for
pure qspinlock usage.
Fixes: ab83647fadae ("riscv: Add qspinlock support")
