Subject: [PATCH v2 3/9] hugetlb: expose hugetlbfs_inode_info in header
Date: Mon, 6 Nov 2017 15:39:38 +0100 [thread overview]
Message-ID: <20171106143944.13821-4-marcandre.lureau@redhat.com> (raw)
In-Reply-To: <20171106143944.13821-1-marcandre.lureau@redhat.com>
hugetlbfs inode information will need to be accessed by code in mm/shmem.c
for file sealing operations. Move inode information definition from .c
file to header for needed access.
