The patch is from 2026; the LTP copyright year should be updated to 2006-2026.

Indentation regressed from two tabs to one. The continuation parameter should
be aligned with the opening parenthesis (or at minimum two tabs to match the
original), per kernel coding style.

Use SAFE_CLOSE() here for consistency.

The EACCES test relies on "nobody" not having write permission to SOCK_FILE.
The socket file's permissions are umask-dependent; with umask 0000 the file
gets mode 0777 and the test would fail spuriously. Add an explicit
`SAFE_CHMOD(SOCK_FILE, 0700)` after the SAFE_BIND() to make this reliable.

Result propagation via shared memory with .forks_child = 1 is correct, but
the exit code is always 0 even on failure. Use `tst_exit()` or exit with the
appropriate code so that unexpected crashes are also caught by the parent.
Alternatively this is a style nit if tst_exit() is not the expected pattern
here.
