We need to hold a reference on the 'dirent' until we are sure there are no more notifications that will be sent. As noted in the new comments we take advantage of the fact that the references are taken and dropped under device_lock() and that nd_device_notify() holds device_lock() over new badblocks notifications. The notifications that happen when badblocks are cleared only occur while the device is active. Also take the opportunity to fix up the error messages to report the user visible effect of a sysfs_get_dirent() failure.

A leftover from the 'bandaid' fix that disabled BTT error clearing in rw_bytes resulted in an incorrect check. After we converted these checks over to use the NVDIMM_IO_ATOMIC flag, the ndns->claim check was both redundant, and incorrect. Remove it.

ACPI 6.2 defines a new ACPI notification value to NVDIMM Root Device in Table 5-169. 0x81 Unconsumed Uncorrectable Memory Error Detected Used to pro-actively notify OSPM of uncorrectable memory errors detected (for example a memory scrubbing engine that continuously scans the NVDIMMs memory). This is an optional notification. Only locations that were mapped in to SPA by the platform will generate a notification. Add support of this notification value by initiating an ARS scan. This will find new error locations and add their badblocks information.

The root cause of panic is the num_pm of nfit_test1 is wrong. Though 1 is specified for num_pm at nfit_test_init(), it must be 2, because nfit_test1->spa_set[] array has 2 elements. Since the array is smaller than expected, the driver breaks other area. (it is often the link list of devres). As a result, panic occurs like the following example.

The rules for which version of the label specification are in effect at any given point in time are as follows: 1/ If a DIMM has an existing / valid index block then the version specified is used regardless if it is a previous version. 2/ By default when the kernel is initializing new index blocks the latest specification version (v1.2 at time of writing) is used. 3/ An environment that wants to force create v1.1 label-sets must arrange for userspace to disable all active regions / namespaces / dimms and write a valid set of v1.1 index blocks to the dimms.

Starting with v1.2 labels, 'address abstractions' can be hinted via an address abstraction id that implies an info-block format. The standard address abstraction in the specification is the v2 format of the Block-Translation-Table (BTT). Support for that is saved for a later patch, for now we add support for the Linux supported address abstractions BTT (v1), PFN, and DAX. The new 'holder_class' attribute for namespace devices is added for tooling to specify the 'abstraction_guid' to store in the namespace label. For v1.1 labels this field is undefined and any setting of 'holder_class' away from the default 'none' value will only have effect until the driver is unloaded. Setting 'holder_class' requires that whatever device tries to claim the namespace must be of the specified class.

The v1.2 namespace label specification requires 'nlabel' and 'position' to be valid for the first ("lowest dpa") label in the set. It also requires all non-first labels to set those fields to 0xff. Linux does not much care if these values are correct, because we can just trust the count of labels with the matching uuid like the v1.1 case. However, we set them correctly in case other environments care. Signed-off-by: NDan Williams <dan.j.williams@intel.com>

The type_guid refers to the "Address Range Type GUID" for the region backing a namespace as defined the ACPI NFIT (NVDIMM Firmware Interface Table).

Previously we only honored the lba size for blk-aperture mode namespaces. For pmem namespaces the lba size was just assumed to be 512.

In support of improved interoperability between operating systems and pre-boot environments the Intel proposed NVDIMM Namespace Specification [1], has been adopted and modified to the the UEFI 2.7 NVDIMM Label Protocol [2]. Update the definitions of the namespace label data structures so that the new format can be supported alongside the existing label format. The new specification changes the default label size to 256 bytes, so everywhere that relied on sizeof(struct nd_namespace_label) must now use the sizeof_namespace_label() helper. There should be no functional differences from these changes as the default is still the v1.1 128-byte format. Future patches will move the default to the v1.2 definition.

acpi_evaluate_dsm() and friends take a pointer to a raw buffer of 16 bytes. Instead we convert them to use guid_t type.
