From: Robert P. J. Day Date: Sun, 13 Apr 2008 01:54:24 +0000 (-0700) Subject: [SCTP]: "list_for_each()" -> "list_for_each_entry()" where appropriate. X-Git-Tag: v2.6.26-rc1~1138^2~129 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=9dbc15f055f05393ace4f1733f160ec3d188cf9b;p=linux-2.6-omap-h63xx.git [SCTP]: "list_for_each()" -> "list_for_each_entry()" where appropriate. Replacing (almost) all invocations of list_for_each() with list_for_each_entry() tightens up the code and allows for the deletion of numerous list iterator variables that are no longer necessary.
