H A D | Makefile | 3d135db5 Mon Aug 02 12:30:05 CDT 2021 Ben Widawsky <ben.widawsky@intel.com> cxl/core: Move memdev management to core
The motivation for moving cxl_memdev allocation to the core (beyond better file organization of sysfs attributes in core/ and drivers in cxl/), is that device lifetime is longer than module lifetime. The cxl_pci module should be free to come and go without needing to coordinate with devices that need the text associated with cxl_memdev_release() to stay resident. The move fixes a use after free bug when looping driver load / unload with CONFIG_DEBUG_KOBJECT_RELEASE=y.
Another motivation for disconnecting cxl_memdev creation from cxl_pci is to enable other drivers, like a unit test driver, to registers memdevs.
