What do you mean by, "device descriptor"? The binary configuration data from the device itself? Kind of like the pci "config" file is in sysfs? If so, then no, I have no objection to including that in sysfs, but call it the "configuration", not a "device descriptor", which is usually read as a "device node" by people like me :) > It would duplicate information that is already available in sysfs in > text form, spread out among several attribute files -- but in a > more-convenient, easier-to-parse package. You mean "binary" package, right? thanks, greg k-h ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
