ocfs2: no need try to truncate file beyond i_size ...
commit 783fda856e1034dee90a873f7654c418212d12d7 upstream.
Linux fallocate(2) with FALLOC_FL_PUNCH_HOLE mode set, its offset can
exceed the inode size. Ocfs2 now doesn't allow that offset beyond inode
size. This restriction is not necessary and violates fallocate(2)
semantics.
If fallocate(2) offset is beyond inode size, just return success and do
nothing further.
Otherwise, ocfs2 will crash the kernel.
kernel BUG at fs/ocfs2//alloc.c:7264!
