Currently you can only have FALLOC_FL_PUNCH_HOLE with FALLOC_FL_KEEP_SIZE set,
so the i_size should not change when hole punching, even when puching the end of
a file off.

+ ->get_sb() is gone. Switch to use of ->mount(). Typically it's just
+a matter of switching from calling get_sb_... to mount_... and changing the
+function type. If you were doing it manually, just switch from setting ->mnt_root
+to some pointer to returning that pointer. On errors return ERR_PTR(...).
