From 19ee5345f23423d5bbd84a59112433592d584b4c Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sat, 24 Sep 2022 06:59:59 +0200 Subject: hugetlbfs: cleanup mknod and tmpfile Duplicate the few lines that are shared between hugetlbfs_mknod() and hugetlbfs_tmpfile(). This is a prerequisite for sanely changing the signature of ->tmpfile().
