+# On each call, this script will update try to aquire the $throttle_lock
+# The first instance acquired the file lock will keep waiting for events
+# to settle and then reload kdump. Other instances will just exit
+# In this way, we can make sure kdump service is restarted immediately
+# and for exactly once after udev events are settled.
