1. Null pointer may be passed to function that may dereference it
   • lustre/mgc/mgc_request.c: in config_log_add, Null pointer 'sptlrpc_cld' that comes from line 315 may be passed to function and can be dereferenced there by passing argument 1 to function 'config_log_put' at line 419.

Changeset 24262 merged on March 9 included a check in config_log_put() for a NULL parameter.  Can this ticket be closed without any further code changes now that config_log_put() cannot dereference a NULL pointer?
