virtiofsd is not ready for multithreading yet. This patch series starts to make the code capable of processing multiple FUSE requests simultaneously. I'm sending these fixes split into several patch series as I make progress auditing the code for thread-safety issues. The final patch series will use a threadpool to process requests from a virtqueue in parallel and it will also enable multiqueue.
Patches 1 & 2 are cleanups discovered when auditing the code. They are not related to multithreading. Stefan Hajnoczi (5): virtiofsd: skip unnecessary vu_queue_get_avail_bytes() virtiofsd: prevent lo_lookup() NULL pointer dereference virtiofsd: make lo_release() atomic virtiofsd: drop lo_dirp->fd field virtiofsd: prevent races with lo_dirp_put() contrib/virtiofsd/fuse_virtio.c | 13 +++--- contrib/virtiofsd/passthrough_ll.c | 71 +++++++++++++++++++++++------- 2 files changed, 60 insertions(+), 24 deletions(-) -- 2.21.0
