Hi All,
I have corefile where we see NULL pointer de-reference PANIC as we have sent
(deliberately) NULL pointer for return value.
vdev_disk_io_start()
error = ldi_ioctl(dvd->vd_lh, zio->io_cmd,
(uintptr_t)&zio->io_dk_callback,
FKIOCTL, kcred, NULL);
Note that it's not just in vdev_disk_io_start() that we pass NULL. It's
everywhere - there are four calls in vdev_disk.c to ldi_ioctl, and they
all pass NULL.
ldi_ioctl() expects last parameter as an integer pointer ( int *rvalp).
I see that in strdoictl().
I'm curious about your configuration. What is the setup you've got that
is going through stream i/o?
Regards,
