That doesn't look right. "DID_TRANSPORT_MARGINAL" occurs at the wrong
position in the array. Please use designated initializers instead of a
traditional array initialization list.


Can you elaborate? From what I see, enum scsi_host_status{ } maps to these strings. So, accordingly, "DID_TRANSPORT_MARGINAL" is placed after "DID_TRANSPORT_FAILFAST" in this array.

Am I missing something obvious?

The above patch places the "DID_TRANSPORT_MARGINAL" string at index 16.
I think that should be index 20 (0x14) instead. From scsi_status.h:

	DID_TRANSPORT_MARGINAL = 0x14, /* Transport marginal errors */

Thanks,

Bart.
