Stefan Hajnoczi acefdde73b virtiofsd: prevent races with lo_dirp_put() ... Introduce lo_dirp_put() so that FUSE_RELEASEDIR does not cause use-after-free races with other threads that are accessing lo_dirp. Also make lo_releasedir() atomic to prevent FUSE_RELEASEDIR racing with itself. This prevents double-frees.
