[PATCH 0/4] IB/core: extended query device caps cleanup for v3.19

[Yann Droneaud <ydroneaud-RlY5vtjFyJ3QT0dZR+AlfA@public.gmane.org>]

Hi,

Following discussions in thread "[PATCH v3 06/17] IB/core: Add support
for extended query device caps" [1], I'm proposing the following patchset
to implement a different behavior to handle the request parameters
in ib_uverbs_ex_query_device() in order to restore the current behavior
of ib_copy_to_udata().

The behavior is different from the initial one but I feel more confident
it would allow a better maintainability. Additionally, I believe it's
looking more like the behavior already implemented by other InfiniBand/RDMA
kernel <-> userspace interfaces.

Yann Droneaud (4):
  IB/uverbs: ex_query_device: fail if output buffer size does not match
  IB/core: ib_copy_to_udata(): don't silently truncate response
  IB/uverbs: ex_query_device: check request's comp_mask
  IB/uverbs: ex_query_device: no need to clear the whole structure
