2011-03-10drbd: Ensure that an epoch contains only requests of one kindPhilipp Reisner1-0/+18
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. Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>

2010-11-27drbd: fix for spin_lock_irqsave in endio callbackLars Ellenberg1-1/+2
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.

2010-10-14drbd: Disable activity log updates when the whole device is out of syncPhilipp Reisner1-0/+4
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.

2010-06-01drbd: fix hang on local read errors while disconnectedLars Ellenberg1-0/+1
"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.
