[dm-devel] [PATCH V6 4/4] block: Limit zone array allocation size

[Martin K. Petersen]

Damien,

> Limit the size of the struct blk_zone array used in
> blk_revalidate_disk_zones() to avoid memory allocation failures
> leading to disk revalidation failure. Also further reduce the
> likelyhood of such failures by using kvcalloc() (that is vmalloc())
> instead of allocating contiguous pages with alloc_pages().
