In file included from drivers/block/drbd/drbd_main.c:54: drivers/block/drbd/drbd_int.h:1190: warning: parameter has incomplete type
Forward declarations of enums do not work.
Fix it unpleasantly by moving the prototype.

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.

In commit 9b7f76dc37919ea36caa9680a3f765e5b19b25fb,

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.

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.

allow the user to select to freeze all IO operations instead of getting
IO errors.

"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.

In particular, several occurances of funny versions of 'success',
'unknown', 'therefore', 'acknowledge', 'argument', 'achieve', 'address',
'beginning', 'desirable', 'separate' and 'necessary' are fixed.

It is force-included on the gcc command line since at least 2.6.15.
Explicit include lines seem to break compilation now in certain configurations.
