3.16.7-ckt15 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx> commit 1ca018d28d96d07788474abf66a5f3e9594841f5 upstream. pnfs_do_write() expects the call to pnfs_write_through_mds() to free the pgio header and to release the layout segment before exiting. The problem is that nfs_pgio_data_destroy() doesn't actually do this; it only frees the memory allocated by nfs_generic_pgio(). Ditto for pnfs_do_read()... Fix in both cases is to add a call to hdr->release(hdr).
