Subjectgetting physical memory of buffer mapped bu kiobuf
hi,
I am mapping user space buffer to kernel space by using kiobufs.
as
..
..
struct kiobuf *iobuf,
alloc_kiovec(1, *iobuf);

map_user_kiobuf() /*for user buffer*/
lock_kiovec();

but to start dma transfers, i must know physical address of mapped pages..
is there any way out???
