Yes, but I think it probably would be better as a separate patch, which: 1. either remove the ccache-stats code & and manual section 2. or issue warning about the obsolete usage. So this patch alone don't affect those are currently using ccache-stats before they migrate to ccache-options. thanks. Roy

I believe there might be a misunderstanding here. You seem to think Thomas suggested to remove ccache-stats because ccache-options now allows to do the same. But in fact, Thomas only suggested to change: """ ifeq ($(BR2_CCACHE),y) ccache-stats: ... endif ifeq ($(BR2_CCACHE),y) ccache-options: ... endif """ by """ ifeq ($(BR2_CCACHE),y) ccache-stats: ... ccache-options: ... endif """ i.e, ccache-stats continues to exist, the only difference with your implementation is that it sits under the same ifeq ($(BR2_CCACHE),y) condition. It's just a minor nit. Best regards, Thomas

It's just a minor nit. Oops, my bad. Could you help do the inline editing when you merge it? thanks.

But most likely, Peter Korsgaard can do it when merging your patch. Thanks a lot for all your quick updates to this patch! Best regards, Thomas
