The code looks fine. However, I would prefer something different for the commit message. Perhaps something like: 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. -- Mike Kravetz > > Signed-off-by: Marc-André Lureau <marcandre.lureau@...hat.com> > --- > fs/hugetlbfs/inode.c | 10 ---------- > include/linux/hugetlb.h | 10 ++++++++++ > 2 files changed, 10 insertions(+), 10 deletions(-) > > diff --git a/fs/hugetlbfs/inode.c b/fs/hugetlbfs/inode.c > index 59073e9f01a4..ea7b10357ac4 100644 > --- a/fs/hugetlbfs/inode.c > +++ b/fs/hugetlbfs/inode.c > @@ -55,16 +55,6 @@ struct hugetlbfs_config { > umode_t mode; > }; > > -struct hugetlbfs_inode_info { > - struct shared_policy policy; > - struct inode vfs_inode; > -}; > - > -static inline struct hugetlbfs_inode_info *HUGETLBFS_I(struct inode *inode) > -{ > - return container_of(inode, struct hugetlbfs_inode_info, vfs_inode); > -} > - > int sysctl_hugetlb_shm_group; > > enum { > diff --git a/include/linux/hugetlb.h b/include/linux/hugetlb.h > index 8bbbd37ab105..f78daf54897d 100644 > --- a/include/linux/hugetlb.h > +++ b/include/linux/hugetlb.h > @@ -278,6 +278,16 @@ static inline struct hugetlbfs_sb_info *HUGETLBFS_SB(struct super_block *sb) > return sb->s_fs_info; > } > > +struct hugetlbfs_inode_info { > + struct shared_policy policy; > + struct inode vfs_inode; > +}; > + > +static inline struct hugetlbfs_inode_info *HUGETLBFS_I(struct inode *inode) > +{ > + return container_of(inode, struct hugetlbfs_inode_info, vfs_inode); > +} > + > extern const struct file_operations hugetlbfs_file_operations; > extern const struct vm_operations_struct hugetlb_vm_ops; > struct file *hugetlb_file_setup(const char *name, size_t size, vm_flags_t acct, >
