From e0f7e2b2f7e7864238a4eea05cc77ae1be2bf784 Mon Sep 17 00:00:00 2001 From: Mike Kravetz Date: Fri, 23 Jul 2021 15:50:44 -0700 Subject: hugetlbfs: fix mount mode command line processing In commit 32021982a324 ("hugetlbfs: Convert to fs_context") processing of the mount mode string was changed from match_octal() to fsparam_u32. This changed existing behavior as match_octal does not require octal values to have a '0' prefix, but fsparam_u32 does. Use fsparam_u32oct which provides the same behavior as match_octal.
