/*
 *--------------------------------------------------------------------------
 *
 * These asserts allow functions to basically (note 1) verify that the caller
 * of the function either has the lock or does not have the lock when calling
 * the function.
 * These asserts only work when "Enable Asserts" and "Enable Kernel Hacking",
 * "Enable Debug Spinlock" and "Enable Debug Mutexes" are selected from
 * the debug selection section of make menuconfig.
 *
 * Note 1: For spinlocks, the check is more actually thorough than the name
 * implies.  HAS_SPINLOCK_COND verifies the caller has the spinlock *AND*
 * the spinlock was acquired on the current CPU.  It should be impossible
 * for the caller to acquire the spinlock on a different CPU and then be
 * migrated to this CPU.
 * NOT_HAS_SPINLOCK verifies the caller does not have the spinlock *AND*
 * the spinlock is not currently held by any other process or thread context
 * on the same CPU.  If it is, the subsequent attempt by this function to
 * acquire the spinlock will deadlock.
