I find CacheFiles gives a valuable performance benefit, but unfortunately is not usable due to hangs. In dmesg "Overlong wait for old active object to go away" (see full message below), and an application will hang or lock, eg. blocking on read(). Sometimes it unblocks, sometimes it seems to hang indefinitely. Is there a higher level explanation for what is going on here? It seems logical that the message is a symptom, rather than the cause itself. What could hold the lock in such a way? The timeout in question appears to be "60 * HZ" in fs/cachefiles/namei.c. I am using the default configuration of cachefilesd, from Git, and kernel 2.6.39.4.
