--- Comment #1 from Xin LI <delphij@FreeBSD.org> ---
delete method can now be selected by kern.cam.da.X.delete_method .

Since this is old hardware, we are closing this as overcome by events instead
of pretending that this is still being worked on.  If it's still important to
distinguish this on modern hardware, please file a new bug with a patch that
creates a quirk to disable the use of ATA_TRIM (DA_Q_NO_UNMAP would disable
ATA_TRIM too so we can't use that one).
