zfs discuss - May 2007 - Re: ZFS over a layered driver interface

Thanks Edward. 
Currently my layered driver does not implement the prop_op(9E) entry point - I
didn''t realize this was necessary since my layered driver worked fine
without it when used over UFS.
My layered driver sits above a ramdisk driver.

I realized the same problem that you''ve mentioned when I was narrowing
in on ldi_get_size() today, and so tried to retrive the N/nblocks property for
the underlying device in my layered driver.
Had some issues with that, and yet to figure it out.

Any pointers on what other stuff the prop_op(9E) entry point should do for a
block driver ?

Thanks,
Shweta.
