Subject: [PATCH rdma-next v1 0/2] Align write() and ioctl() paths
Date: Thu, 16 Jul 2020 13:39:54 +0300
Message-ID: <> (raw)

From: Leon Romanovsky <>

 * v0 revealed old bug
  that took a while to find.
 * create_cq() was rewritten to make sure that uobj is properly initialized.


The discussion about RWQ table patch revealed incosistency with use of
usecnt, complex unwind flows without any reason and difference between
write() and ioctl() paths.

This series extends infrastructure to be consistent, reliable and
predicable in regards of commit/desotry uobject.


Leon Romanovsky (2):
  RDMA/core: Align abort/commit object scheme for write() and ioctl()
  RDMA/core: Update write interface to use automatic object lifetime
