74 * This IOCTL wrapper allows the guest to make an HGCM call from user space. The
75 * OS-independant part of the Guest Additions already contain code for making an
76 * HGCM call from the guest, but this code assumes that the call is made from the
77 * kernel's address space. So before calling it, we have to copy all parameters
78 * to the HGCM call from user space to kernel space and reconstruct the structures
79 * passed to the call (which include pointers to other memory) inside the kernel's
80 * address space.
81 *
82 * @returns 0 on success or Linux error code on failure
83 * @param arg User space pointer to the call data structure
