So: lock_kernel(); lock_kernel(); unlock_kernel(); unlock_kernel(); is perfectly ok. The lock_kernel() code detects that the calling thread already owns the lock and just increments current->lock_depth. Under linux locks are non-recursive EXCEPT for lock_kernel() (aka the BLK or "big kernel lock") See lib/kernel_lock.c for more details. -Mitch - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | |||||||||
