[PATCH rdma-next v2 00/17] Provide per-ID access to restrack objects

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Leon Romanovsky <leonro@xxxxxxxxxxxx>

Changelog:
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

--------------------------------------------------------------------
The series convert 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.

Thanks
