state of the I/O memory when arrives at low level HBA driver
Hi,
This may be petty question, but I am not really sure about this.
When a I/O comes to the low level SCSI HBA driver
through enqueue() interface,
can it happen that I/O data memory is paged out or can be paged out?
I mean, doing DMA mapping such as pci_map_single() provides, just physical addresses or it also (page-in if requires) followed by locking the page(s) in the system?
Regards,
Parav Pandit

o.k. I got the answer.
It is already been locked when it comes to the low level HBA driver.
Thanks,
Parav
