Here are some patches to fix locking and invalidation in the smb3/cifs
fallocate, in particular in zero_range, punch_hole, collapse_range and
insert_range.

Those four operations were, for the most part, missing calls to inode_lock(),
filemap_invalidate_lock() and truncate_pagecache_range(), the last of which
was causing generic/031 to show data corruption.
