Wondering if "before uprobes are remove from rbtree." > sounds as if more than one uprobe is being removed at one > instance. The sentence still does not parse: " X waits until Ys that have done Z before A is removed from the rbtree" Did you want to say: " The current unregistering thread waits till all other threads have hit a breakpoint, to acquire the uprobes_treelock before the uprobe is removed from the rbtree. " (I have removed 'that' and added a comma.)
