From: zhong jiang <zhongjiang@huawei.com>
Since 'commit 3e89e1c5ea84 ("hugetlb: make mm and fs code explicitly non-modular")' bring in the mainline. mount hugetlbfs will result in the following issue.
mount: unknown filesystme type 'hugetlbfs'
because previous patch remove the module_alias_fs, when we mount the fs type, the caller get_fs_type can not find the filesystem.
The patch just recover the module_alias_fs to identify the hugetlbfs.
