[PATCH bpf-next 2/4] tools/resolve_btfids: Check objects before removing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We want this clean to be called from tree's root clean
and that one is silent if there's nothing to clean.

Adding check for all object to clean and display CLEAN
messages only if there are objects to remove.
