This usually happens when there are large # number of namespaces created in the region backed by the dimm and the # label-index spans max possible config-area. An error of the form below # usually reported in the kernel logs: # # [ 255.293912] nvdimm: probe of nmem0 failed with error -22 # # The patch fixes these validation checks there by letting libnvdimm # access the entire config-area. # # Fixes: 53e80bd042773('powerpc/nvdimm: Add support for multibyte read/write for metadata') # Signed-off-by: Vaibhav Jain # Reviewed-by: Aneesh Kumar K.V #
