That is a goal for me yes.
Elimination of unnecessary stuff from kernel.h is useful.

$ grep -r --include=*.[ch] NIPQUAD *
include/linux/kernel.h:#define NIPQUAD(addr) \
include/linux/kernel.h:#define NIPQUAD_FMT "%u.%u.%u.%u"
net/netfilter/ipvs/ip_vs_ftp.c: sprintf(buf, "%u,%u,%u,%u,%u,%u",
NIPQUAD(from.ip),
As of right now NIPQUAD_FMT is unused and
could be removed from kernel.h
There's 1 use of NIPQUAD.
Maybe instead of removal the #define could be
moved to netfilter.h or netfilter_ipv4.h
Another is to consolidate the two uses of
"%u,%u,%u,%u,%u,%u"
$ grep -r --include=*.[ch] "%u,%u,%u,%u,%u,u%" *
fs/cachefiles/bind.c: _enter("{%u,%u,%u,%u,%u,%u},%s",
net/ipv4/netfilter/nf_nat_ftp.c: return snprintf(buffer, buflen,
"%u,%u,%u,%u,%u,%u",
net/netfilter/ipvs/ip_vs_ftp.c: sprintf(buf, "%u,%u,%u,%u,%u,%u",
NIPQUAD(from.ip),
Maybe these 2 open coded sprintf/snprintf could be
consolidated and moved to an appropriate include
like netfilter_ipv4 or another.
What do you suggest?
