I have scanned through the scsi tree and checked all places that used SG_ALL. Those drivers that where not ready for SG_ALL to mean "any size" where changed to what ever is appropriate for this driver. Mainly 3 groups. Those that meant SG_ALL == 255: [PATCH 1/8] firewire: ieee1394: Move away from SG_ALL [PATCH 2/8] scsi-drivers Don't use SG_ALL as allocation size Those who are not sg-chaining ready: [PATCH 3/8] NCR5380: Not sg-chain ready [PATCH 4/8] wd33c93: Not sg-chain ready [PATCH 5/8] arm/scsi: Not sg-chain ready [PATCH 6/8] scsi: Drivers not ready for sg-chaining And those that just got confused: [PATCH 7/8] a100u2w: advansys: initio: Wrong use of SG_ALL And finally the switch of SG_ALL to ~0, that is MAX_ what ever type it is. [PATCH 8/8] Change SG_ALL to mean "any size" Please request if you want any patches squashed or split. These are based on the scsi-bidi git-tree and mainly on top of the: "[SCSI] remove use_sg_chaining" patch. James do you want that I reverse the dependency so your patch will be on top of these patches?
