| vread | vread() - read vmalloc area in a safe way.*@buf: buffer for reading data*@addr: vm address.*@count: number of bytes to be read.* This function checks that addr is a valid vmalloc'ed area, and* copy data from that area to a given buffer | 
| vwrite | vwrite() - write vmalloc area in a safe way.*@buf: buffer for source data*@addr: vm address.*@count: number of bytes to be read.* This function checks that addr is a valid vmalloc'ed area, and* copy data from a buffer to the given addr | 
| remap_vmalloc_range_partial | map_vmalloc_range_partial - map vmalloc pages to userspace*@vma: vma to cover*@uaddr: target user address to start at*@kaddr: virtual address of vmalloc kernel memory*@size: size of map area* Returns: 0 for success, -Exxx on failure* This function checks |
