objtool: Print top level commands on incorrect usage
Print top-level objtool commands, along with the error on incorrect command line usage. Objtool command line parser exit's with code 129, for incorrect usage. Convert the cmd_usage() exit code also, to maintain consistency across objtool. After the patch: $ ./objtool -j Unknown option: -j usage: objtool COMMAND [ARGS] Commands: check Perform stack metadata validation on an object file orc Generate in-place ORC unwind tables for an object file $ echo $? 129 Signed-off-by: Kamalesh Babulal <[email protected]> Acked-by: Josh Poimboeuf <[email protected]> Cc: Linus Torvalds <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Thomas Gleixner <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Ingo Molnar <[email protected]>
