[PATCH] zcache: Use WARN_ON_SMP in ASSERT_SPINLOCK

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



As the description of WARN_ON_SMP in bug.h says, one can not use
spin_is_locked() in assertions for non‐SMP configurations, because it
always returns the lock is not held. Otherwise a warning is thrown
everytime on a uniprocessor system.
