The patches from Eric, that add support for so called ctl_paths
has recently being accepted, so I hope we can start using this
very useful feature.
To begin with, I switched the core kernel code to use the paths.
The rest code to be patched (after this set) will be:
* arch-specifi,
* some filesystems,
* networking.
After this set the total vmlinux size decrease is ~500 bytes:
add/remove: 5/6 grow/shrink: 5/1 up/down: 121/-616 (-495)
function old new delta
mq_sysctl_path - 24 +24
fs_quota_path - 24 +24
uts_root_path - 16 +16
sd_ctl_path - 16 +16
ipc_root_path - 16 +16

dquot_init 191 196 +5
uts_root_table 88 - -88
sys_table 88 - -88
sd_ctl_root 88 - -88
mq_sysctl_root 88 - -88
mq_sysctl_dir 88 - -88
ipc_root_table 88 - -88
fs_table 792 704 -88
The set is prepared to fit the 2.6.24-rc3-mm2 kernel with Eric's
patches concerning sysctls.
