Hi,
In order to remove ambiguity on the order of series, I combined three
series into one, which does from the beginning (nldev and restrack
refactoring through IDs exposure upto initial object cleanup).
No change to userspace posted earlier.
Thanks
-------------------------------------------------------------------------
Changelog:
v2->v3:
* Rebased on to -rc4
* Removed special XA markings (RES_VISIBLE)
* Dropped HW ID allocator for now.
* Removed xa_is_err() check in *_byid() function
* Reworded commit messages to reflect changes
* Fixed compilation warning due to my changes to rdmavt
v1->v2:
* Added "Fortify .." atch, it helps to find uninitialized paths
* Rewrote ".doit" patch
v0->v1:
* Don't set mark in case restrack entry failed to be added
* Fix typos
* Move kdoc comments from restrack.h to restrack.c
* Rewrote user/kernel marking patch to drop xa_set_mark in favour
of "user" field
* Fixed two panics with uninitialized values, one for QPs and
another for ibdev in CM_ID
--------------------------------------------------------------------
1. Refactoring and ID exposure parts:
This part converts internal restrack DB implementation from hash-based
to be XArray-based. Such change is needed to allow access per specific
index for .doit callbacks. In addition, such index will provide ability
to bind/unbind counters to specific QPs, provide valuable debug
information about parent object (e.g. PD of specific QP, or context
of specific PD) and get list of objects connected to specific context.
2. PD cleanup:
In this part, I converted all drivers to use IB/core ib_pd allocation
to ensure that ib_device pointer is valid.
3. Parent ID exposure:
This small part exposes IDs and parent IDs to use to query specific objects.
An example of how it can be extended to support multiple contexts for PD
was posted to the ML in previous discussions.
Thanks
