[PATCH rdma-next V1 0/8] Export vendors specific ABIs

[Leon Romanovsky]

The consolidate library revealed the fact that vendor specific
structures and defines are copy/pasted between kernel and user-space.

This patch set moves these headers from internal driver directory to common
place and unifies their name to be drivername-abi.h, so it will be easily shared
by numerous libraries supported in https://github.com/linux-rdma/rdma-core.git.

The drivers which were NOT handled in this patch set are mthca (dead code), hfi, qib,
rxe, usnic and i40iw.

Available in the "topic/uapi-abi" topic branch of this git repo:
git://git.kernel.org/pub/scm/linux/kernel/git/leon/linux-rdma.git

[PATCH rdma-next V1 1/8] IB/mlx5: Move and decouple user vendor structures

[Leon Romanovsky]

This patch decouples and moves vendors specific structures to
common UAPI folder which will be visible to all consumers.

These structures are used by user-space library driver
(libmlx5) and currently manually copied to that library.

This move will allow cross-compile against these files and
simplify introduction of vendor specific data.

[PATCH rdma-next V1 2/8] IB/cxgb3: Move user vendor structures

[Leon Romanovsky]

This patch moves cxgb3 vendor's specific structures to
common UAPI folder which will be visible to all consumers.

These structures are used by user-space library driver
(libcxgb3) and currently manually copied to that library.

This move will allow cross-compile against these files and
simplify introduction of vendor specific data.

[PATCH rdma-next V1 4/8] IB/mlx4: Move user vendor structures

[Leon Romanovsky]

This patch moves mlx4 vendor's specific structures to
common UAPI folder which will be visible to all consumers.

These structures are used by user-space library driver
(libmlx4) and currently manually copied to that library.

This move will allow cross-compile against these files and
simplify introduction of vendor specific data.

[PATCH rdma-next V1 5/8] IB/ocrdma: Move user vendor structures

[Leon Romanovsky]

This patch moves ocrdma vendor's specific structures to
common UAPI folder which will be visible to all consumers.

These structures are used by user-space library driver
(libmlx4) and currently manually copied to that library.

This move will allow cross-compile against these files and
simplify introduction of vendor specific data.

In addition, it changes types to be __uXX instead of uXX.

[PATCH rdma-next V1 6/8] IB/nes: Move user vendor structures

[Leon Romanovsky]

This patch moves nes vendor's specific structures to
common UAPI folder which will be visible to all consumers.

These structures are used by user-space library driver
(libmlx4) and currently manually copied to that library.

This move will allow cross-compile against these files and
simplify introduction of vendor specific data.

I had asked this to Leon offline but he recommended to ask on the ML.

What happens if this shared functionality is split between multiple files? Can we 
just add them in the same folder (so uapi/rdma/provider-abi1.h,
uapi/rdma/provider-abi2.h, etc.)?

Sure, I guess, but there should be a reasonably good reason why you
want the file split ..
