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).
