vmalloc question

["Rohit Hooda" <hooda.rohit@xxxxxxxxx>]

Hi,

I have one query about using vmalloced buffers. 

Can we give vmalloced buffers to tcp_recvmsg() to get data from the
network stack? Does the tcp_recv routine use this buffer passed to it
for DMA? 

or

Can we give vmalloced buffers to sock_recvmsg() to get data from the
network stack? sock_recvmsg() calls sock->ops->recvmsg()which
uses this buffer .... the recvmsg call here is call to tcp_recvmsg() ?
Does the tcp_recv routine use this buffer passed to it for DMA? 


Thanks,
-Rohit
