Since you are okay with this will make this change, except the array
name should be:- nvme_zrasf_to_blk_zcond.

Yes.

Please see the explanation at the end [1].

I'll add a BLK_STS_OK check before the assignment.

if transfer len matches the rw len and it is zero we cannot send any data
so just complete the command.

[1] Zone Mgmt send emulation with all bit comment :-
I ran the test where all the zones are set to the EMPTY right after creating
a controller on the host (initiator), see [A]. With the passthru command
with
all bit set, I was able to change the state of all the zones, see [B].
So I did not understand your comment about how all bit is failing to
change the
state of all zones with passthru commnd ?
A. All zones are empty.

B. Now we send the passthru command with all bit set for
zsa values RESET 0x04, OPEN 0x03, CLOSE 0x01, FINISH 0x02
in the same oder as above. All the zones state are changed.
