[LTP] [PATCH v14 0/3] open16: allow restricted O_CREAT of FIFOs and regular files

[Wei Gao]

v13->v14:
   * Swapped informal "Level 1/2" descriptions for actual sysctl values 1 and 2.
   * Moved local sysctl macros to the global include/tst_path_defs.h header.
   * Use designated initializers.
   * Flat-nested the child process path by using SAFE_FORK() with an early parent return.
   * Replaced conditional branch logic with the unified TST_EXP_FD_OR_FAIL() macro.
   * Add 8 missing CVE tags associated with the kernel commit.

Wei Gao (3):
  lib/tst_uid: Remove spurious TERRNO from tst_get_free_gid success path
  lib: New library function tst_get_free_uid
