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/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-ld --version # < git log --format=%s --max-count=1 612ee81b9461475b5a5612c2e8d71559dd3c7920 # < make -s -j 120 ARCH=arm O=/kisskb/build/powerpc-next_versatile_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- versatile_defconfig # make -s -j 120 ARCH=arm O=/kisskb/build/powerpc-next_versatile_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:204:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:338:21: note: 'pdeo' was declared here /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2591:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1852:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] WARNING: "return_address" [vmlinux] is a static EXPORT_SYMBOL_GPL Completed OK # rm -rf /kisskb/build/powerpc-next_versatile_defconfig_arm # Build took: 0:00:23.443608
