Hi, Trond was able to see the mm bug that caused LOCALIO to fail to find the page in the pagecache (resulting in filemap_read hitting an infinite loop), see: https://marc.info/?l=linux-nfs&m=172625026100876&w=2 With that filemap fix generic/525 works with LOCALIO. Hopefully that resolves any doubts you had about LOCALIO? DO you think it ready to be merged? Thanks, Mike
