| |
Hi all, this is the fifth version of the patch "xen: modify kernel mappings corresponding to granted pages":
changes to v4:
- add many more comments to the code;
- fix some code style issues;
- use set_page_private/page_private macros;
- compare with GNTST_general_error rather than -1;
- BUG in case map->pages are highmem;
Changes to v3:
- move the xen_mc_entry call in m2p_remove_override after the xen_mc_flush call;
- use false rather than 0 as a parameter to alloc_xenballooned_pages;
- update the m2p_add_override call in blkback.c, following the new interface;
- fix few code style issues.
Changes to v2:
- drop highmem support;
- fold the multicall patch into the main patch;
- add another patch to extend the alloc_xenballooned_pages interface with an highmem parameter that allows the caller to explicitly request for highmem or lowmem pages;
- modify gntdev to use lowmem pages only thanks to the new alloc_xenballooned_pages interface.
Shortlog and diffstat follow:
