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 <vaibhav@linux.ibm.com> # Reviewed-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20190927062002.3169-1-vaibhav@linux.ibm.com # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 612ee81b9461475b5a5612c2e8d71559dd3c7920 # < make -s -j 80 ARCH=sparc64 O=/kisskb/build/powerpc-next_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- defconfig # make -s -j 80 ARCH=sparc64 O=/kisskb/build/powerpc-next_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] WARNING: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned.
