drbd: Ensure that an epoch contains only requests of one kind
The assert in drbd_req.c:755 forces us to have only requests of
one kind in an epoch. The two kinds we distinguish here are:
local-only or mirrored.

drbd: fix for spin_lock_irqsave in endio callback
In commit 9b7f76dc37919ea36caa9680a3f765e5b19b25fb,
Author: Lars Ellenberg <lars.ellenberg@linbit.com>
Date: Wed Aug 11 23:40:24 2010 +0200
drbd: new configuration parameter c-min-rate
a bad chunk slipped through, which is now reverted as well,
restoring the correct irqsave for the endio callback.
This patch also add comments at both req_mod()
and in the endio callback so it should not happen again.

drbd: Disable activity log updates when the whole device is out of sync
When the complete device is marked as out of sync, we can disable
updates of the on disk AL. Currently AL updates are only disabled
if one uses the "invalidate-remote" command on an unconnected,
primary device, or when at attach time all bits in the bitmap are
set.
As of now, AL updated do not get disabled when a all bits becomes
set due to application writes to an unconnected DRBD device.
While this is a missing feature, it is not considered important,
and might get added later.
BTW, after initializing a "one legged" DRBD device
drbdadm create-md resX
drbdadm -- --force primary resX
AL updates also get disabled, until the first connect.

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.
