Which version of compiler? Well, latest change of namei_vfat.c is Sep, 2016. And I can't reproduce it by "gcc version 6.3.0 20170516 (Debian 6.3.0-18)". > CC [M] fs/fat/namei_vfat.o > In file included from ./arch/x86/include/asm/string.h:2:0, > from ./include/linux/string.h:18, > from ./include/linux/bitmap.h:8, > from ./include/linux/cpumask.h:11, > from ./arch/x86/include/asm/cpumask.h:4, > from ./arch/x86/include/asm/msr.h:10, > from ./arch/x86/include/asm/processor.h:20, > from ./arch/x86/include/asm/cpufeature.h:4, > from ./arch/x86/include/asm/thread_info.h:52, > from ./include/linux/thread_info.h:37, > from ./arch/x86/include/asm/preempt.h:6, > from ./include/linux/preempt.h:80, > from ./include/linux/spinlock.h:50, > from ./include/linux/seqlock.h:35, > from ./include/linux/time.h:5, > from ./include/linux/stat.h:18, > from ./include/linux/module.h:10, > from fs/fat/namei_vfat.c:18: > fs/fat/namei_vfat.c: In function ‘vfat_add_entry’: > ./arch/x86/include/asm/string_32.h:74:16: warning: array subscript is above > array bounds [-Warray-bounds] > *((char *)to + 4) = *((char *)from + 4); > ~~~~~~~~~~~~^~~~ > ./arch/x86/include/asm/string_32.h:74:16: warning: array subscript is above > array bounds [-Warray-bounds] > ./arch/x86/include/asm/string_32.h:78:17: warning: array subscript is above > array bounds [-Warray-bounds] > *((short *)to + 2) = *((short *)from + 2); > ~~~~~~~~~~~~~^~~~ > ./arch/x86/include/asm/string_32.h:78:17: warning: array subscript is above > array bounds [-Warray-bounds] > ./arch/x86/include/asm/string_32.h:82:15: warning: array subscript is above > array bounds [-Warray-bounds] > *((int *)to + 1) = *((int *)from + 1); > ~~~~~~~~~~~^~~~ > ./arch/x86/include/asm/string_32.h:82:15: warning: array subscript is above > array bounds [-Warray-bounds] -- OGAWA Hirofumi <hirof...@mail.parknet.co.jp>
