[PATCH v2 3/9] hugetlb: expose hugetlbfs_inode_info in header

From: Marc-Andrà Lureau
Date: Mon Nov 06 2017 - 09:40:12 EST


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.
