Subject: [PATCH v2 0/2] qnx4: Avoid confusing compiler about buffer lengths

Hi,

This attempts to fix the issue Ronald Monthero found[1]. Avoids using a
too-short struct buffer when reading the string, by using the existing
struct union.

v2:
 - Use BUILD_BUG_ON() instead of _Static_assert()
v1: https://lore.kernel.org/all/20231118032638.work.955-kees@kernel.org/

Kees Cook (2):
  qnx4: Extract dir entry filename processing into helper
  qnx4: Use get_directory_fname() in qnx4_match()
