Subject: [PATCH 0/2] Simplify some of the locking in vfio_group
Date: Thu, 29 Sep 2022 11:59:23 -0300	[thread overview]
Message-ID: <0-v1-917e3647f123+b1a-vfio_group_users_jgg@nvidia.com> (raw)

Kevin points out that the vfio_group->users doesn't really need to exist
now, and some other inspection shows that the group_rwsem has outlived its
utility as well. Replace both with simpler constructs.

Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>

Jason Gunthorpe (2):
  vfio: Remove the vfio_group->users and users_comp
  vfio: Change vfio_group->group_rwsem to a mutex
