No, the server does not need to implement rollback, and does not in fact need to check for the return value of the fuse_reply_create() call unless it wants to mess with interrupts (not enabled by default). See libfuse/lib/fuse.c where most of the fuse_replu_XXX() calls just ignore the return value. Thanks, Miklos
