| |
Hi,
The comment for the smp_wmb() in prepare_uprobe() says:
"pairs with rmb() in find_active_uprobe()"
but I see no (smp_)rmb() in find_active_uprobe(); I see the smp_rmb() in handle_swbp(): is this the intended pairing barrier?
Which memory accesses do you want to "order" with this pairing?
Thanks, Andrea
