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
