uprobes: Introduce MMF_RECALC_UPROBES Add the new MMF_RECALC_UPROBES flag, it means that MMF_HAS_UPROBES can be false positive after remove_breakpoint() or uprobe_munmap(). It is also set by uprobe_dup_mmap(), this is not optimal but simple. We could add the new hook, uprobe_dup_vma(), to set MMF_HAS_UPROBES only if the new mm actually has uprobes, but I don't think this makes sense. The next patch will use this flag to clear MMF_HAS_UPROBES. Signed-off-by: Oleg Nesterov <oleg@redhat.com> Acked-by: Srikar Dronamraju <srikar@linux.vnet.ibm.com>
