From 69b6a3b159927d45092f64e07f40d5ecf93e11d8 Mon Sep 17 00:00:00 2001 From: Philipp Reisner Date: Tue, 20 Dec 2011 11:49:58 +0100 Subject: [PATCH] drbd: restart loop in drbd_make_request() [prepare for Linux-3.2] With Linux-3.2 generic_make_request() will no longer loop over the request function until it finally returns 0. Move this loop into our drbd_make_request() function.
