Subject: [patch 15/15] hugetlbfs: fix mount mode command line processing
Date: Fri, 23 Jul 2021 15:50:44 -0700 [thread overview]
Message-ID: <20210723225044.DpiHGbzxj%akpm@linux-foundation.org> (raw)
In-Reply-To: <20210723154926.c6cda0f262b1990b950a5886@linux-foundation.org>
From: Mike Kravetz <mike.kravetz@oracle.com>
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.
