Hi In running kernel there are many places you can look to get the usage. But the bottom line is
* You can take a spinlock under a mutex. e.g. mutex_lock--->spinlock-----critical section-----spinunlock--->mutex_unlock. * You can not take a mutex under a spinlock. e.g. spinlock--->mutex_lock -----critical section ....mutex_unlock---->spinunlock is not allowed.
