Description

Pair Parser_exit() with Parser_init() call under lfs and lctl. Which was not done earlier. lfs and lctl binary both calls same set of routines under libcfs/libcfs/util/parser.c. So, although both are different binarys, they could be handled under same ticket. This also free's memory allocated via strdup().
