The vast majority of files including object-store.h did not need dir.h nor khash.h. Split the header into two files, and let most just depend upon object-store-ll.h, while letting the two callers that need it depend on the full object-store.h. After this patch: $ git grep -h include..object-store | sort | uniq -c 2 #include "object-store.h" 129 #include "object-store-ll.h" Diff best viewed with `--color-moved`.
