Hi Peter, Linus, Greg, The cond_guard() patch has gone through several rounds of review and is looking good to me, but is missing feedback from one of you that have been grappling with a cross-kernel view of what these new facilities should look like. Separately I have been running into trouble trying to fit no_free_ptr() into some cleanup patches and thought of another way to build on the conditional syntax originated in scoped_cond_guard(). More specifically, scoped_cond_guard() introduced the concept of passing a statement to the macro to handle the failure case. cond_guard() extends that to be used within an existing scope to automatically release a conditionally acquired lock rather than defining a new scope. The cond_no_free_ptr() helper takes that concept for ending the cleanup scope for objects when responsibility for freeing them has been transferred to a 3rd object or subsystem. --- Dan Williams (1): cleanup: Introduce cond_no_free_ptr() Fabio M.
