Since the information exposed by this # attribute cannot be cached it is better to ward off access to this # attribute from users who don't need to access to these performance # statistics. # # Hence update the access mode of 'perf_stats' attribute to be only # readable by root users. # # Fixes: 2d02bf835e57 ("powerpc/papr_scm: Fetch nvdimm performance stats from PHYP") # Reported-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> # Signed-off-by: Vaibhav Jain <vaibhav@linux.ibm.com> # Reviewed-by: Ira Weiny <ira.weiny@intel.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20200907110540.21349-1-vaibhav@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux-ld --version # < git log --format=%s --max-count=1 0460534b532e5518c657c7d6492b9337d975eaa3 # < make -s -j 24 ARCH=ia64 O=/kisskb/build/powerpc-fixes_ia64-defconfig_ia64-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux- defconfig # < make -s -j 24 ARCH=ia64 O=/kisskb/build/powerpc-fixes_ia64-defconfig_ia64-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux- help # make -s -j 24 ARCH=ia64 O=/kisskb/build/powerpc-fixes_ia64-defconfig_ia64-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux- olddefconfig # make -s -j 24 ARCH=ia64 O=/kisskb/build/powerpc-fixes_ia64-defconfig_ia64-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] In file included from /kisskb/src/arch/ia64/include/uapi/asm/intrinsics.h:22:0, from /kisskb/src/arch/ia64/include/asm/intrinsics.h:11, from /kisskb/src/arch/ia64/include/asm/timex.h:14, from /kisskb/src/include/linux/timex.h:65, from /kisskb/src/include/linux/time32.h:13, from /kisskb/src/include/linux/time.h:73, from /kisskb/src/fs/nfs/read.c:11: /kisskb/src/fs/nfs/read.c: In function 'nfs_read_completion': /kisskb/src/arch/ia64/include/uapi/asm/cmpxchg.h:57:2: warning: value computed is not used [-Wunused-value] ((__typeof__((ptr))) __xchg((unsigned long) (x), (ptr), sizeof((ptr)))) ^ /kisskb/src/fs/nfs/read.c:196:5: note: in expansion of macro 'xchg' xchg(&nfs_req_openctx(req)->error, error); ^ /kisskb/src/fs/nfs/read.c: In function 'nfs_readpage': /kisskb/src/arch/ia64/include/uapi/asm/cmpxchg.h:57:2: warning: value computed is not used [-Wunused-value] ((__typeof__((ptr))) __xchg((unsigned long) (x), (ptr), sizeof((ptr)))) ^ /kisskb/src/fs/nfs/read.c:355:2: note: in expansion of macro 'xchg' xchg(&ctx->error, 0); ^ No errors detected in 22420 functions.
