[PATCH] register_chrdev_region() leak and race fix · a9007553

Andrew Morton authored Mar 28, 2003

- If two CPUs run register_chrdev_region(major == 0) at the same time they
  can get the same major.

  Fix that by extending the lock coverage.

- local variable `cd' was leaky on an error path.

- Add some API commentary.
