From 74027f4a181754e917853bd1d2e21449f008ab39 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Tue, 4 Feb 2014 13:47:26 -0500 Subject: [PATCH] cifs_iovec_read(): resubmit shouldn't restart the loop ... by that point the request we'd just resent is in the head of the list anyway. Just return to the beginning of the loop body...
