Time for proper scsi discard support. The first patch is for the block layer to implement the discard granularity limits properly. The second is a SPC3r20 compliant implementation sending WRITE SAME with the unmap bit from sd. ATA support will come later now that I finally obtained a TRIM capable OCZ SSD. So far only tested using Martin's scsi_debug TP support and my experimental qemu TP support, but I'll be able to test it on some real arrays soon. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
