With the escaping of special characters in patch https://review.whamcloud.com/37764 "LU-11407 tgt: cleanup job_stats output printing" and truncation of log JobIds in patch https://review.whamcloud.com/49351 "LU-16376 obdclass: NUL terminate long jobid strings" it may be that the requested "clear" of a specific JobID in lprocfs_jobstats_seq_write(), considering that the format printed via "lctl get_param ..job_stats" does not match the internal name stored for the job.

The written JobID to clear should be de-quoted, un-escaped and then truncated to match the 32-char JobID that is stored internally in ojs_hash.
