It's not really that difficult.
Those files are created in Fedora by the kernel rpm %post, which does this..
find $RPM_BUILD_ROOT/lib/modules/$KernelVer -name "*.ko" -type f >modnames
fgrep /drivers/ modnames | xargs --no-run-if-empty nm -upA |
sed -n 's,^.*/\([^/]*\.ko\): *U \(.*\)$,\1 \2,p' > drivers.undef
collect_modules_list()
{
sed -r -n -e "s/^([^ ]+) \\.?($2)\$/\\1/p" drivers.undef |
LC_ALL=C sort -u > $RPM_BUILD_ROOT/lib/modules/$KernelVer/modules.$1
}
collect_modules_list networking \
'register_netdev|ieee80211_register_hw|usbnet_probe'
collect_modules_list block \
'ata_scsi_ioctl|scsi_add_host|blk_init_queue|register_mtd_blktrans|scsi_esp_register'
This looks complicated, but it really boils down to
"create a list of modules that use these symbols"
Rather than add this to every distros kernel packages though, it could
be done as part of depmod, and moved to module-init-tools.
