Different issue and I just stumbled upon it when testing this. The =
quirk provided for the SSD 320 drives,
{
/*
* Intel 320 Series SSDs
* 4k optimised & trim only works in 4k requests + 4k =
aligned
*/
{ T_DIRECT, SIP_MEDIA_FIXED, "*", "INTEL SSDSA2CW*", "*" =
},
/*quirks*/ADA_Q_4K
},
{
/*
* Intel 330 Series SSDs
* 4k optimised & trim only works in 4k requests + 4k =
aligned
*/
{ T_DIRECT, SIP_MEDIA_FIXED, "*", "INTEL SSDSC2CT*", "*" =
},
/*quirks*/ADA_Q_4K
},
doesn't match mine, hence they are not properly recognized.
Anyway, as Steve says, it's irrelevant. If I change the min_auto_ashift =
variable to 12 it should set the ashift to 12
regardless of the quirk detection.
I'll send the updated quirk to -scsi, but that's a different matter.
Borja.
