Merge branch 'for-jens' of git://git.drbd.org/linux-drbd into for-3.5/drivers
Philipp writes: This are the updates we have in the drbd-8.3 tree. They are intended for your "for-3.5/drivers" drivers branch. These changes include one new feature: * Allow detach from frozen backing devices with the new --force option; configurable timeout for backing devices by the new disk-timeout option And huge number of bug fixes: * Fixed a write ordering problem on SyncTarget nodes for a write to a block that gets resynced at the same time. The bug can only be triggered with a device that has a firmware that actually reorders writes to the same block * Fixed a race between disconnect and receive_state, that could cause a IO lockup * Fixed resend/resubmit for requests with disk or network timeout * Make sure that hard state changed do not disturb the connection establishing process (I.e. detach due to an IO error). When the bug was triggered it caused a retry in the connect process * Postpone soft state changes to no disturb the connection establishing process (I.e. becoming primary). When the bug was triggered it could cause both nodes going into SyncSource state * Fixed a refcount leak that could cause failures when trying to unload a protocol family modules, that was used by DRBD * Dedicated page pool for meta data IOs * Deny normal detach (as opposed to --forced) if the user tries to detach from the last UpToDate disk in the resource * Fixed a possible protocol error that could be caused by "unusual" BIOs. * Enforce the disk-timeout option also on meta-data IO operations * Implemented stable bitmap pages when we do a full write out of the bitmap * Fixed a rare compatibility issue with DRBD's older than 8.3.7 when negotiating the bio_size * Fixed a rare race condition where an empty resync could stall with if pause/unpause events happen in parallel * Made the re-establishing of connections quicker, if it got a broken pipe once. Previously there was a bug in the code caused it to waste the first successful established connection after a broken pipe event. PS: I am postponing the drbd-8.4 for mainline for one or two kernel development cycles more (the ~400 patchets set).
