Unless Aneesh has another reason for the patch, it should be reverted
to preserve hugetlb page sharing locking.
I guess we want to take this patch as a revert patch rather than
dropping the one in -mm. That would help in documenting the i_mmap_mutex
locking details in commit message. Or may be we should add necessary
comments around the locking ?
Code comments would be better if possible - we shouldn't force people to
dig around in git history to understand small code snippets.
