Subject: [UNIX] Move the unix sock iterators in to proper place
X-Git-Tag: v2.6.25-rc1~1162^2~1358
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=a53eb3feb2718bf906e81be89fae823b9b6157b6;p=linux-2.6-omap-h63xx.git

[UNIX] Move the unix sock iterators in to proper place

The first_unix_socket() and next_unix_sockets() are now used
in proc file and in forall_unix_socets macro only.

The forall_unix_sockets is not used in this file at all so
remove it. After this move the helpers to where they really
belong, i.e. closer to proc code under the #ifdef CONFIG_PROC_FS
option.
