Re: [dm-devel] SCSI Sense patch



Hi Alasdair,

I take it you are referring to the addition of “bi_error” to the bio data structure. Any idea when an alternate solution will be available, is it still in the discussion phase ?

Thanks
 Bart Brooks

Unfortunately not because (1) upstream has decided not to use them but
to work towards an alternative way of achieving the same goal; and
(2) the patches involve a change to an important data structure that
might cause pre-compiled modules unconnected with device-mapper to cause
corruption.
