Hi, This patch against 2.6.12-rc4 adds a void * field to the base sysfs attribute, and updates all the derived attributes (device_attribute, etc) to pass the void * to their sysfs callbacks. This facilitates a number of things: - reduce the size of much of the sysfs attribute code significantly by allowing the replacement of the large number of macro generated virtually identical sysfs callbacks with a single sysfs callback that uses the void * parameter to decide what to do. For example, adapting adm1026 to take advantage of this patch: -------------------2.6.11.7-------------------- Module Size Used by adm1026 44692 0 --------2.6.12-rc3-devdyncallback----- Module Size Used by adm1026 33172 0 (see http://archives.andrew.net.au/lm-sensors/msg31310.html) - allow the creation of a non-predetermined and potentially unlimited number of sysfs attributes, this is required by bmcsensors - a driver I am porting from lm_sensors 2.4 to 2.6. (see http://archives.andrew.net.au/lm-sensors/msg31225.html , http://bmcsensors-26.sourceforge.net/) This first patch changes the core sysfs attribute and derived attributes.
