If anyone has any objections, please let me know. ------------------ From: Josef Bacik commit a01c8e5b1dff1ce489e6b339139e744db36b8bb3 upstream. A write to a "uevent" file which is no valid action makes kobject_synth_uevent() print a warning and uevent_store() an error every time. This is generally considered a bad thing so rate limit these messages.
