This patch has been added to the 3.18 stable tree. If you have any
objections, please let us know.
===============
[ Upstream commit 1ca018d28d96d07788474abf66a5f3e9594841f5 ]
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).
