[PATCH v9 0/1] perf jevents: Check the keys of the JSON tables

[TAKANO Mitsuhiro]

v9 of the check.  The two points the review raised about the argument are
fixed, and the one about the tree is still left alone on purpose.

  - --check on a directory that is not there used to report nothing and
    exit 0, because nothing found under it reads the same as a tree with
    no bad key.  It now says so on stderr and exits 2, which is the code
    the test already uses for "could not run".
  - "--check=DIR" is taken as well as "--check DIR".  The option is read
    before the parser looks at the three positional arguments, so the
    value could be left over and taken for the table directory.

The check itself is unchanged: walk, set difference against the list of 51
keys, print the file that carries the bad key, exit 1.  On today's tree it
reports 19 keys in four tables:

  arch/arm64/ampere/ampereonex/mmu.json    PublicDescrition   16 objects
  arch/x86/amdzen4/cache.json              BriefDescript6ion   1 object
  arch/x86/amdzen5/load-store.json         BriefDescript6ion   1 object
  arch/x86/amdzen6/load-store.json         BriefDescript6ion   1 object

The point about the test checking a temporary table and never the tables
in the tree is right, and it is still not possible to add: the tree
carries the two misspellings above, and a test that fails the day it lands
is not one anyone wants.  Once the patches that fix them are in, the test
can run against the tree as well - I would rather add that as a second
step than bake a list of known-bad files into the test now.

Changes since v8:

  - --check reports a directory that is not there instead of passing it
  - "--check=DIR" is accepted as well as "--check DIR"
