Missing kernel-doc comment for SAFE_FILE_VPRINTF(). Public macros added to
include/tst_safe_file_ops.h must be documented with kernel-doc syntax
recognized by linuxdoc.

Using sizeof("coredump02") as the length argument triggers a
-Wsizeof-pointer-memaccess compiler warning from TST_EXP_EQ_STRN(). Use
TST_EXP_EQ_STR(info.pr_fname, "coredump02") since pr_fname is
null-terminated, or pass sizeof(info.pr_fname).

Verdict - Needs revision
