Subject[PATCH v3 0/4] cxl/mem: Fix memdev device setup
From
Date
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.

Dan Williams (4):
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
