The later includes the former and in addition to `seastar::format()`, `print.hh` also provides helpers like `seastar::fprint()` and `seastar::print()`, which are deprecated and not used by scylladb. Previously, we include `seastar/core/print.hh` for using `seastar::format()`. and in seastar 5b04939e, we extracted `seastar::format()` into `seastar/core/format.hh`. this allows us to include a much smaller header. In this change, we just include `seastar/core/format.hh` in place of `seastar/core/print.hh`. Signed-off-by: Kefu Chai <kefu.chai@scylladb.com> Closes scylladb/scylladb#21574
