Subject: [PATCH v3 0/4]  cxl/mem: Fix memdev device setup
Date: Tue, 30 Mar 2021 16:36:26 -0700
Message-ID: <161714738634.2168142.10860201861152789544.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)

Changes since v2: [1]
- switch from non-idiomatic srcu synchronization of the device
  registration state to rwsem protection of the cxlmd->cxlm pointer.
  (Jason)

A collection of fixes initially inspired by Jason's recognition of
dev_set_name() error handling mistakes on other driver review, but also
from a deeper discussion of idiomatic device operation shutdown flows.
The end result is easier to reason about and validate. Thank you, Jason.

The sysfs_emit() fixup and unpublishing of device power management files
are independent sanity cleanups.

      cxl/mem: Use sysfs_emit() for attribute show routines
      cxl/mem: Fix synchronization mechanism for device removal vs ioctl operations
      cxl/mem: Do not rely on device_add() side effects for dev_set_name() failures
      cxl/mem: Disable cxl device power management
