1428  如果allows us to skip the uprobe_mmap if there are no uprobe events active* at this time. Probably a fine grained per inode count is better?()或非valid_vma: Verify if the specified vma is an executable vma* Relax restrictions while unregistering: vm_flags might have* changed after breakpoint was inserted则返回
1431  如果非atomic_read( & mm_users)则返回
1434  如果非test_bit(has uprobes , & flags)或test_bit(MMF_HAS_UPROBES can be wrong , & flags)则返回
1438  如果vma_has_uprobes(vma, start, end)则设置内存位
