[PATCH 2/2 net-2.6.26] [NETNS]: Compilation warnings under CONFIG_NET_NS.

[Denis V. Lunev]

Recent commits from YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org>
have been introduced a several compilation warnings
'assignment discards qualifiers from pointer target type'
due to extra const modifier in the inline call parameters of
{dev|sock|twsk}_net_set.

Drop it.

Applied.

Too bad allmodconfig doesn't enable things which are y/n only.

We are in trouble for this right now :( there we do not work with SYSFS
enabled right now.

Sorry for the typo.

Unfortunately, NET_NS depends on !SYSFS,
so allyesconfig might not help...

Eric Biederman told us he has community acceptance for his approach and 
he will push sysfs per namespace in a few weeks.

Right now NET_NS can be more or less reliably selected via:

    echo '# CONFIG_SYSFS is not set' >foo
    echo 'CONFIG_NET_NS=y'           >>foo
    KCONFIG_ALLCONFIG=foo make allmodconfig

But this trick a) doesn't work with some options, b) likely to break when
someone will start selecting SYSFS.
