iov_iter_fault_in

Name:Fault in one or more iovecs of the given iov_iter, to a maximum length of* bytes. For each iovec, fault in each page that constitutes the iovec.* Return 0 on success, or non-zero if the memory could not be accessed (i.e.* because it is an invalid address).

Proto:int iov_iter_fault_in_readable(struct iov_iter *i, size_t bytes)

Type:int

Parameter:

Type	Parameter	Name
struct iov_iter *	i
size_t	bytes

skip = iov_offset

If Not (* Bit 0 is the read/write bit, set if we're writing. * Bit 1 is the BVEC_FLAG_NO_REF bit, set if type is a bvec and * the caller isn't expecting to drop a page reference when done. & (ITER_BVEC | ITER_KVEC)) Then
