I put the sg v4 structure in sg.h simply I thought bsg.h is for kernel space and some user-space programs need to include sg.h for some old ioctl stuff even if they use only sg v4. > > I've uploaded simple programs to just read/write by using SG v4: > > > > http://www.kernel.org/pub/linux/kernel/people/tomo/sg4/ > > Great! > > I'll get this reviewed and merged as soon as I can, probably monday. Thanks. The patchset is on the top of the two minor patches: http://marc.theaimsgroup.com/?l=linux-scsi&m=116621265732083&w=2 http://marc.theaimsgroup.com/?l=linux-scsi&m=116621265731963&w=2 The latter needs small modifications if you will change blk_rq_unmap_user interface. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
