As mentioned, rescan-scsi-bus.sh is keeping references to /proc/scsi as
a fall back only, as it's meant to work kernel independent. Per default
it'll be using /sys, and will happily work without /proc/scsi.
So it's really only /proc/scsi/sg which carries some meaningful
information; maybe we should move/copy it to somewhere else.
I personally like getting rid of /proc/scsi.
/proc/scsi/device_info doesn't seem to be in sysfs.
Could the contents of /proc/scsi/sg/* be placed in
/sys/class/scsi_generic/* ? Currently that directory only has symlinks
to the sg devices.
The sg parameters are already available in /sys/module/sg/parameters;
so from that perspective I feel we're good.
# ls /sys/module/sg/parameters/
allow_dio def_reserved_size scatter_elem_sz
# ls /proc/scsi/sg/
allow_dio debug def_reserved_size device_hdr devices device_strs
red_debug version
So that doesn't work, what are in 'parameters' are passed in at
module/driver initialization. Back to my original question: Could the
contents of /proc/scsi/sg/* be placed in /sys/class/scsi_generic/* ?
Problem is /proc/scsi/device_info, for which we currently don't have any
other location to store it at.
Hmm.
