pooka 4d6a407bdd Process flush requests from the file server in a separate thread
context.  This fixes a long-standing but seldomly seen deadlock,
where the kernel was holding pages busy (due to e.g. readahead
request) while waiting for the server to respond, and the server
made a callback into the kernel asking to invalidate those pages.
... or, well, theoretically fixes, since I didn't have any reliable
way of repeating the deadlock and I think I saw it only twice.
