[PATCHv3 0/5] perf/hw_breakpoint: Fix breakpoint modify

hi, Milind reported that modify_user_hw_breakpoint wouldn't allow the breakpoint changing if the new attr had 'disabled' set to true. I found a case where it actualy prevents ptrace user interface to change the breakpoint. It's described in patch 1 as perf test, patch 2 is the breakpoint code
