allocate_hugepages() writes to the kernel sysfs file to allocate hugepages in the Kata VM. However, even if the write succeeds, it's not certain that the kernel will actually be able to allocate as many hugepages as we requested. This patch reads back the file after writing it to check if we were able to allocate all the required hugepages. fixes #3816 Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
