From: Li Zhang <[email protected]> vol-clone reports out of memory error with disk type on ppc64.
Currently, wbytes is defined as size_t type which is 8 bytes on ppc64, but args's value in ioctl(fd, args..) in kernel is unsigned int. So it will read more 4 bytes by ioctl() with size_t from memory which gets a large number and causes out of memory error. This patch changes size_t to unsigned int to synchronize with kernel.
