stable inclusion from stable-5.10.54 commit 92291fa2d144b13a761578cb40d36d37e7f332ee bugzilla: 175586 https://gitee.com/openeuler/kernel/issues/I4DVDU
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit e0f7e2b2f7e7864238a4eea05cc77ae1be2bf784 upstream.
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.
