That's better but:
* the subject (first line of commit msg) should be about what the patch
  actually does, usally with a prefix of the subsystem. So for example:
  cifs: remove deadstore in cifs_close_all_deferred_files()
* the body of the commit msg should be wrapped around 80 cols to avoid
  long lines unless you are quoting some output or urls

Cheers,
