Such a situation may lead to an unexpected RCU stall,\nwhere the callback repeatedly queuing the expire update, as reported\nby fuzzer.\n\nThis patch introduces a sanity check of the timer start tick time, so\nthat the system returns an error when a too small start size is set.\nAs of this patch, the lower limit is hard-coded to 100us, which is\nsmall enough but can still work somehow." } ],
