From: Jim Cromie <jim.cromie at gmail.com> Heres 2 patches to shrink object size of hwmon/pc87360 driver 1. hwmon-pc87360-use-sensor-attr-2.patch Converts SENSOR_ATTRs to SENSOR_ATTR_2s for all sysfs-callbacks. Also adds a number of #defines which provide values used to initialize the sensor_device_attr_2.nr field for each sensor. 2. hwmon-pc87360-sysfs-combo-callbacks.patch This combines individual (show|set)_Sensor_Attr callbacks into (show|set)_Sensor callbacks that handle all that Sensor's Attrs. The callback routines use the .nr field to determine what attribute they were called for. Combining callbacks results in a non-trivial size reduction (b4, after) 14588 3224 16 17828 45a4 A-2/drivers/hwmon/pc87360.ko 13124 3224 16 16364 3fec A-3/drivers/hwmon/pc87360.ko ie about 9% Combining all show_X (for all X) together is possible, but would compromise clarity, and would save only ~ 1/5 th additional space. These were tested against 2.6.16 + 4 patches from -mm1 (-mm1 is panic'g at boot on this NFS-root box) Id like to see these get into -mm2
