This patchset is the userspace portion of the knfsd client name tracking overhaul. See this patch series for an explanation: nfsd: overhaul the client name tracking code The main changes from the last set are: - a bunch of cleanups and better patch "division" for bisectability - the daemon will downcall with an error now when given an upcall command that it doesn't recognize - it now uses inotify to wait for the pipe instead of polling - more comprehensive autoconf tests for required headers and libraries - it's disabled from the build by default. You need to configure with --enable-nfsdcld to turn it on. Steve felt that this would help smooth the transition for distro packagers. - a manpage and README update have been added The daemon listens for upcalls on the rpc_pipefs pipe using libevent, and handles the requests from the kernel. The data is stored using a sqlite database. The main reason for this is that it takes care of most of the fussy details and atomicity concerns of tracking the information on stable storage. For now, the daemon is only suitable for single-host configurations. My plan is to later extend this to be suitable for clustered configurations as well. At this point, I think the daemon is ready for inclusion. It would be good for it to make the next nfs-utils release to coincide with the kernel patches going into 3.3.
