In a first step, each resource has exactly one connection, and both objects are allocated at the same time. The final result will be one resource and zero or more connections. Only allow to delete a resource if all its connections are C_STANDALONE. Stop the worker threads of all connections early enough. Signed-off-by:

In a setup where a device (aka volume) can replicate to multiple peers and one connection can be shared between multiple devices, we need separate objects to represent devices on peer nodes and network connections. As a first step to introduce multiple connections per device, give each drbd_device object a single drbd_peer_device object which connects it to a drbd_connection object. Signed-off-by:

Currently, of_match_node compares each given match against all node's compatible strings with of_device_is_compatible. To achieve multiple compatible strings per node with ordering from specific to generic, this requires given matches to be ordered from specific to generic. For most of the drivers this is not true and also an alphabetical ordering is more sane there. Therefore, this patch introduces a function to match each of the node's compatible strings against all given compatible matches without type and name first, before checking the next compatible string. This implies that node's compatibles are ordered from specific to generic while given matches can be in any order. If we fail to find such a match entry, then fall-back to the old method in order to keep compatibility. Cc: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> Signed-off-by:

Merge tag 'trace-fixes-v3.14-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull twi tracing fixes from Steven Rostedt: "Two urgent fixes in the tracing utility. The first is a fix for the way the ring buffer stores timestamps. After a restructure of the code was done, the ring buffer timestamp logic missed the fact that the first event on a sub buffer is to have a zero delta, as the full timestamp is stored on the sub buffer itself. But because the delta was not cleared to zero, the timestamp for that event will be calculated as the real timestamp + the delta from the last timestamp. This can skew the timestamps of the events and have them say they happened when they didn't really happen. That's bad. The second fix is for modifying the function graph caller site. When the stop machine was removed from updating the function tracing code, it missed updating the function graph call site location. It is still modified as if it is being done via stop machine. But it's not. This can lead to a GPF and kernel crash if the function graph call site happens to lie between cache lines and one CPU is executing it while another CPU is doing the update. It would be a very hard condition to hit, but the result is severe enough to have it fixed ASAP" * tag 'trace-fixes-v3.14-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace/x86: Use breakpoints for converting function graph caller ring-buffer: Fix first commit on sub-buffer having non-zero delta
