Masami Hiramatsu (Google) a6e2a0e414 tracing/probes: Fix to record 0-length data_loc in fetch_store_string*() if fails ... [ Upstream commit 797311bce5c2ac90b8d65e357603cfd410d36ebb ] Fix to record 0-length data to data_loc in fetch_store_string*() if it fails to get the string data. Currently those expect that the data_loc is updated by store_trace_args() if it returns the error code. However, that does not work correctly if the argument is an array of strings. In that case, store_trace_args() only clears the first entry of the array (which may have no error) and leaves other entries. So it should be cleared by fetch_store_string*() itself. Also, 'dyndata' and 'maxlen' in store_trace_args() should be updated only if it is used (ret > 0 and argument is a dynamic data.)
