I notice that the ata drivers in HEAD do not use anymore bioq_disksort, but rather they have their own routine, (ad_queue_request() in turn calling ata_sort_queue()) which probably does something similar. I wonder: 1) how different is ata_sort_queue() from bioq_disksort() in terms of design ? 2) is there any strong reason for this change ? 3) any pointers to mail threads where this changes have been discussed ? I cannot find any relevent comments browsing the code or CVS. the change was introduced here +++ src/sys/dev/ata/ata-disk.c 2005/03/30 12:03:37 1.183 so not long ago... cheers luigi
