It uses optional script arugment to define polling folder with default value "/dev". The script is polling that folder and uses "diff" utility to detect changes in the output. Here is the script run with current target folder and new 1, 2 files playing role of new devices. $ ./hwdetect.sh .

On read from the “list” attr. it shows content of the linked list. On write to the “list” attr. it adds new string to the linked list. Since the list items separator is not specified - content is shown as it was inserted including line endings. This gives flexibility of using "echo" with "-n" argument and without.

Existing "wimbledone" module already has sysfs interface "/sys/kernel/wimbledon/list". By reading and wrinting this file "show" and "store" callbacks are called and counted. With this update the module creates a folder "wimbeldon" and child files: * "/proc/wimbeldon/nshow" Returns amount of show callbacks (cat /sys/kernel/wimbledon/list) * "/proc/wimbeldon/nstore" Returns amount of store callbacks (echo >> /sys/kernel/wimbledon/list) * "/proc/wimbeldon/auth_name" Returns module author name Output from the orange board is attached.

Existing "wimbledone" module already has sysfs interface
"/sys/kernel/wimbledon/list". By reading and wrinting this
file "show" and "store" callbacks are called and counted.
With this update the module creates a folder "wimbeldon" and
child files:
"/proc/wimbeldon/nshow"
Returns amount of show callbacks (cat /sys/kernel/wimbledon/list)
"/proc/wimbeldon/nstore"
Returns amount of store callbacks (echo >> /sys/kernel/wimbledon/list)
"/proc/wimbeldon/auth_name"
Returns module author name
