Subject: sendpage and high mem pages
Date: Thu, 20 Apr 2006 14:29:06 -0500	[thread overview]
Message-ID: <4447E102.5080203@cs.wisc.edu> (raw)

I was wondering if it is ok to pass sendpage high mem pages. If a piece
of code does this:

struct socket *sock;

sock->ops->sendpage(pg...)

and pg is a highmem page will the network layer do the right thing or
should the caller check the page type and call sock_no_sendpage() for
highmen? It looks like net/sunrpc/xprtsock.c does a check but
drivers/scsi/iscsi_tcp.c and some others do not.
