LinuxLists.cc - [PATCH bpf-next v2] net: don't include filter.h from net/sock.h

2021-12-29 00:49:24

Subject: [PATCH bpf-next v2] net: don't include filter.h from net/sock.h

sock.h is pretty heavily used (5k objects rebuilt on x86 after
it's touched). We can drop the include of filter.h from it and
add a forward declaration of struct sk_filter instead.
This decreases the number of rebuilt objects when bpf.h
is touched from ~5k to ~1k.

There's a lot of missing includes this was masking. Primarily
in networking tho, this time.

It would be nice if we used the number of files rebuilt because of a
header file change as another metric that the kernel is evaluated with
from release to release (or even on a commit by commit basis). Food for
thought.

Maybe Andy has some thoughts, he has been working on dropping
unnecessary includes of kernel.h, it seems.

It'd be cool to plug something that'd warn us about significant
increases in dependencies into the patchwork build bot.

I have one more small series which un-includes uapi/bpf.h from
netdevice.h at which point I hope we'll be largely in the clear
from build bot performance perspective.
