On top of "kill uprobes_state->count, add MMF_HAS_UPROBES" series. Once again, I am not sure we really need this (except 1/3). Perhaps we could remove uprobe_munmap() instead and forget about the false-positive MMF_HAS_UPROBES's. OTOH, imho it looks a bit more clean this way. Please comment. diffstat reports the code bloat, but note that the previous series removed more code.
