Notes: Currently IOs on RAW devices gets submitted as 512 byte buffer heads. This patch improves it by doing 4K buffer heads when possible. But this causes variable size buffer heads in a single IO request. There is a concern in the community that, all the low level drivers can not handle this. In order to address their concern, I restricted my patch to work only for SCSI and only with the drivers which advertise that they can handle variable size buffer heads in a single request. This can be done by adding following line to driver scsi_host_template: can_do_varyio:1 |
