commit 0db1d53937fafa8bb96e077375691e16902f4899 upstream.
The callers of vfs_iter_write() are required to hold file_start_write().
file_start_write() is a no-op for the S_ISBLK() case, but it is really
needed when the backing file is a regular file.
We are going to move file_{start,end}_write() into vfs_iter_write(), but
we need to fix this first, so that the fix could be backported to stable
kernels.
