DESCRIPTION¶
The

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