Subject: [PATCH v3 01/40] cxl: Rename CXL_MEM to CXL_PCI
Date: Sun, 23 Jan 2022 16:28:44 -0800	[thread overview]
Message-ID: <164298412409.3018233.12407355692407890752.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <164298411792.3018233.7493009997525360044.stgit@dwillia2-desk3.amr.corp.intel.com>

From: Ben Widawsky <ben.widawsky@intel.com>

The cxl_mem module was renamed cxl_pci in commit 21e9f76733a8 ("cxl:
Rename mem to pci"). In preparation for adding an ancillary driver for
cxl_memdev devices (registered on the cxl bus by cxl_pci), go ahead and
rename CONFIG_CXL_MEM to CONFIG_CXL_PCI. Free up the CXL_MEM name for
that new driver to manage CXL.mem endpoint operations.
