Hi David, I tested your recent patches, with much better results. Many thanks for these. I didn't do formal testing, but I've not yet seen the "Overlong wait" message in an hour or so of use, which is excellent. But now that I can reasonably use fscache with NFS, I noticed that the page cache doesn't seem to be used? * When cachefilesd is running, reads do not come from the page cache * The page cache fills up with something, but the local cache filesystem continues to be read * If the page cache was populated before cachefilesd was launched (ie. with NFS pages), then these are successfully used I tested using a set of large image files which fit in RAM. In the first cases, I'm not sure if the page cache memory contains NFS pages, or local disk pages. Is there an easy way to check? This test is on v2.6.39.4, with the recent patches applied. I didn't need to modify any code, as long as I included one other fscache patch since that version. It seems that v3.0 onward does not boot on my hardware, which is something I need to look into separately.
