vn_isdisk -- checks if a vnode represents a disk
vn_isdisk(struct vnode *vp, int *errp);
The vn_isdisk() function checks to see if vp represents a disk. In order
for vp to be a disk, it must be a character device, v_rdev must be valid,
and the cdevsw entry's flags must have D_DISK set.
Its arguments are:
vp The vnode to check.
errp An integer pointer to store the error number in if the call fails.
If the vnode represents a disk, 1 is returned; otherwise, 0 is returned
and errp will contain the error number.
