checkpatch would warn you not to do this. Use msleep(20) to keep it
quiet.

And this won't compile:
drivers/scsi/aacraid/linit.c: In function ‘aac_acquire_resources’:
drivers/scsi/aacraid/linit.c:1395:16: error: ‘IRQF_DISABLED’ undeclared
(first use in this function)
IRQF_SHARED|IRQF_DISABLED, "aacraid",
Please run checkpatch and compile against the kernel you're submitting
for. The reason for this failure is that IRQF_DISABLED got eliminated
from the kernel somewhere in the 3.x series.
