Debian                                            July 9, 2001                                      VN_ISDISK(9)

       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.

       vn_isdisk — checks if a vnode represents a disk

       If  the  vnode represents a disk, 1 is returned; otherwise, 0 is returned and errp will contain the error
       number.
