Jim Shu e124670f0b kernel/spinlock: Fix a SMP race condition of SPIN_VALIDATE ... z_spin_lock_valid() reads shared variable twice to do two checkings. If this variable is modified by other CPU between two read accesses, the checking value is inconsistent. This inconsistency causes the error that CPU0 can pass the checking when it doesn't hold spinlock because zeroed-out thread_cpu value is ambiguous with the CPU0 ID. Fix the inconsistency by only reading shared variable once and using local variable value to do two checkings. Fixes #19299. Signed-off-by: Jim Shu <cwshu@andestech.com>		2019-09-26 16:51:38 -04:00
