drbd: fix max_segment_size initialization

2010-01-22T10:34:54+00:00

blk_queue_make_request() internally calls blk_set_default_limits(),
so calling blk_queue_max_segment_size() before is useless.
Ergo: move the call to blk_queue_max_segment_size() down a few lines.

Impact:
If, after a fresh modprobe, you first connect a Diskless drbd,
then attach, this could result in a DRBD Protocol Error at first.
The next connection attempt would then succeeded.

drbd: check on CONFIG_LBDAF, not LBD

2010-01-07T13:07:11+00:00

It is called LBDAF since 2.6.31.

impact:
without this change, on 32bit,
DRBD would wrongly claim to only support 2TiB devices.

drivers/block/drbd: Correct NULL test

2010-01-04T10:51:41+00:00

Test the just-allocated value for NULL rather than some other value.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// 
@@
expression x,y;
statement S;
@@

x = \(kmalloc\|kcalloc\|kzalloc\)(...);
(
if ((x) == NULL) S
|
if (
-   y
+   x
       == NULL)
 S
)
//

drbd: Silenced an assert that could triggered after changing write ordering method

2009-12-31T08:33:09+00:00

Immediately after changing the write ordering method, the epoch can already
be finished at this point.

drbd: Kconfig fix

2009-12-29T16:38:28+00:00

!CONFIG_OPT evalues to FALSE if CONFIG_OPT='m'. Do not display the
"DRBD disabled..." message if the dependencies are compiled as module.

drbd: Fix for a race between IO and a detach operation [Bugz 262]

2009-12-29T16:36:40+00:00

In D_DISKLESS we do not hand out any new references to ldev (local_cnt)
therefore waiting until all previously handed out refereces got returned
is sufficient before actually freeing mdev->ldev.
