Christoph Hellwig 34dc93c2fc pnfs/blocklayout: allocate separate pages for the layoutcommit payload ... Instead of overflowing the XDR send buffer with our extent list allocate pages and pre-encode the layoutupdate payload into them. We optimistically allocate a single page use alloc_page and only switch to vmalloc when we have more extents outstanding. Currently there is only a single testcase (xfstests generic/113) which can reproduce large enough extent lists for this to occur.
