With all the recent refactoring around struct btree op struct search has gotten rather large. But we can now easily break it up in a different way - we break out struct btree_insert_op which is for inserting data into the cache, and that's now what the copying gc code uses - struct search is now specific to request.c Signed-off-by: Kent Overstreet <kmo@daterainc.com>
