Make sure that the zone write pointer offset array is allocated with a
vmalloc in dm_zone_revalidate_cb() by passing GFP_KERNEL gfp flag to
kvcalloc(). However, since we do not want to trigger IOs while
revalidating zones, change dm_revalidate_zones() to have the zone scan
done in GFP_NOIO context

Hello Damien Le Moal,
The patch bb37d77239af: "dm: introduce zone append emulation" from

Hi,
May I get a copy of source code for devmapper 1.02.110 & 1.02.137 to keep as
our reference?
Thanks
