From a742b02c75e6e76bd0833f9b6e702f1be7d7e008 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Mon, 14 Mar 2011 12:41:26 -0400 Subject: [PATCH] xen/blkback: Use kzalloc's, and GFP_KERNEL for data structures. The patch titled:"xen/blkback: Use 'vzalloc' for page arrays and pre-allocate pages." allocates the structures and its member variables using the 'vzalloc'. Daniel Stodden pointed out that vzalloc is good when we use big number of pages - while these are at the max two pages. We can do this using kzalloc. Also the GFP_HIGHMEM does not work properly with Xen, so take that out. We will have to revisit this when a "get_empty_pages_and_pagevec" type API shows up to leverage that.
