However, it is # not available to loadable modules. Leading to errors such as: # # ERROR: "numa_slit" [drivers/nvme/host/nvme-core.ko] undefined! # # The error above is caused by the nvme multipath code that makes # use of node_distance for its path calculation. When the patch was # added, the lightnvm subsystem would select nvme and always compile # it in, leading to the node_distance call to always succeed. # However, when this requirement was removed, nvme could be compiled # in as a module, which exposed this bug. # # This patch extracts node_distance to a function and exports it. # Since ACPI is depending on node_distance being a simple lookup to # numa_slit, the previous behavior is exposed as slit_distance and its # users updated. # # Fixes: f333444708f82 "nvme: take node locality into account when selecting a path" # Fixes: 73569e11032f "lightnvm: remove dependencies on BLK_DEV_NVME and PCI" # Signed-off-by: Matias Bjøring <mb@lightnvm.io> # Signed-off-by: Tony Luck <tony.luck@intel.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/s390x-linux/bin/s390x-linux-gcc --version # < git log --format=%s --max-count=1 ef78e5ec9214376c5cb989f5da70b02d0c117b66 # < make -s -j 8 ARCH=s390 O=/kisskb/build/linus_s390-defconfig_s390x CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/s390x-linux/bin/s390x-linux- defconfig # make -s -j 8 ARCH=s390 O=/kisskb/build/linus_s390-defconfig_s390x CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/s390x-linux/bin/s390x-linux- /kisskb/src/kernel/cgroup/cgroup-v1.c: In function 'cgroup1_mount': /kisskb/src/kernel/cgroup/cgroup-v1.c:1256:20: warning: 'root' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:186:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/mm/hugetlb.c: In function 'alloc_pool_huge_page': /kisskb/src/mm/hugetlb.c:1433:5: warning: 'page' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/net/tun.c: In function 'tun_get_user': /kisskb/src/drivers/net/tun.c:1823:30: warning: 'copylen' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/net/tun.c:1733:46: warning: 'linear' 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:341:21: note: 'pdeo' was declared here Completed OK # rm -rf /kisskb/build/linus_s390-defconfig_s390x # Build took: 0:02:42.047889
