File libparted-Add-support-for-NVDIMM-devices.patch of Package parted
From: Sebastian Parschauer <sparschauer@suse.de> Date: Mon, 23 Oct 2017 17:47:47 +0200 Subject: Add support for NVDIMM devices References: bsc#1064446 Patch-mainline: v3.3 Git-commit: 71885c5f493f3a5d950adbb3e8d17eff7e023053 Recognize NVDIMM devices, so that "parted -s /dev/pmem7 p" now prints "Model: NVDIMM Device (pmem)" instead of "Model: Unknown (unknown)". In order for a device to be recognized as NVDIMM, it has to have a 'blkext' major number. But since this major can be used also by other device types, we also check that the device path contains 'pmem' as a substring. * include/parted/device.h.in(PedDeviceType): Add PED_DEVICE_PMEM * libparted/arch/linux.c(_device_probe_type): Recognize NVDIMM devices. * libparted/arch/linux.c(linux_new): Handle NVDIMM devices. * parted/parted.c(do_print): Add "pmem" to list of transports.
