From d255e5ff5fc6cc6c60dd014d1261448a7bbc8134 Mon Sep 17 00:00:00 2001 From: Lars Ellenberg Date: Thu, 27 May 2010 09:45:45 +0200 Subject: drbd: fix hang on local read errors while disconnected "canceled" w_read_retry_remote never completed, if they have been canceled after drbd_disconnect connection teardown cleanup has already run (or we are currently not connected anyways). Fixed by not queueing a remote retry if we already know it won't work (pdsk not uptodate), and cleanup ourselves on "cancel", in case we hit a race with drbd_disconnect.
