When you hit the half-way mark of the highres # multiplier, small highres movements will incorrectly translate into big # traditional wheel movements, causing odd jitters. # # Simplify the code and make the output stable. # # NOTE! I'm pretty sure this will need further tweaking. But this at # least turns a unusable mouse wheel on my Logitech MX Anywhere 2S into # a usable one. # # Cc: Jiri Kosina <jikos@kernel.org> # Cc: Harry Cutts <hcutts@chromium.org> # Cc: Benjamin Tissoires <benjamin.tissoires@redhat.com> # Cc: Peter Hutterer <peter.hutterer@who-t.net> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < git log --format=%s --max-count=1 044ee890286153a1aefb40cb8b6659921aecb38b # < make -s -j 8 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # yes \n \| make -s -j 8 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 8 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- In file included from /kisskb/src/include/linux/bitmap.h:9, from /kisskb/src/include/linux/cpumask.h:12, from /kisskb/src/arch/x86/include/asm/paravirt.h:17, from /kisskb/src/arch/x86/include/asm/irqflags.h:68, from /kisskb/src/include/linux/irqflags.h:16, from /kisskb/src/include/linux/rcupdate.h:39, from /kisskb/src/include/linux/rculist.h:11, from /kisskb/src/include/linux/pid.h:5, from /kisskb/src/include/linux/sched.h:14, from /kisskb/src/kernel/debug/kdb/kdb_support.c:15: In function 'strncpy', inlined from 'kallsyms_symbol_next' at /kisskb/src/kernel/debug/kdb/kdb_support.c:239:4: /kisskb/src/include/linux/string.h:253:9: warning: '__builtin_strncpy' specified bound depends on the length of the source argument [-Wstringop-overflow=] return __builtin_strncpy(p, q, size); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/kernel/debug/kdb/kdb_support.c: In function 'kallsyms_symbol_next': /kisskb/src/include/linux/string.h:274:10: note: length computed here return __builtin_strlen(p); ^~~~~~~~~~~~~~~~~~~ /kisskb/src/lib/ubsan.c:432:1: warning: ignoring attribute 'noreturn' in declaration of a built-in function '__ubsan_handle_builtin_unreachable' because it conflicts with attribute 'const' [-Wattributes] { ^ <built-in>: note: previous declaration here In file included from /kisskb/src/include/linux/bitmap.h:9, from /kisskb/src/include/linux/cpumask.h:12, from /kisskb/src/arch/x86/include/asm/cpumask.h:5, from /kisskb/src/arch/x86/include/asm/msr.h:11, from /kisskb/src/arch/x86/include/asm/processor.h:21, from /kisskb/src/arch/x86/include/asm/cpufeature.h:8, from /kisskb/src/arch/x86/include/asm/thread_info.h:53, from /kisskb/src/include/linux/thread_info.h:38, from /kisskb/src/arch/x86/include/asm/preempt.h:7, from /kisskb/src/include/linux/preempt.h:81, from /kisskb/src/include/linux/spinlock.h:51, from /kisskb/src/include/linux/seqlock.h:36, from /kisskb/src/include/linux/time.h:6, from /kisskb/src/include/linux/stat.h:19, from /kisskb/src/include/linux/module.h:10, from /kisskb/src/lib/test_hexdump.c:8: In function 'strncpy', inlined from 'test_hexdump_prepare_test.constprop' at /kisskb/src/lib/test_hexdump.c:102:3: /kisskb/src/include/linux/string.h:253:9: warning: '__builtin_strncpy' specified bound depends on the length of the source argument [-Wstringop-overflow=] return __builtin_strncpy(p, q, size); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/lib/test_hexdump.c: In function 'test_hexdump_prepare_test.constprop': /kisskb/src/include/linux/string.h:274:10: note: length computed here return __builtin_strlen(p); ^~~~~~~~~~~~~~~~~~~ /kisskb/src/scripts/unifdef.c: In function 'Mpass': /kisskb/src/scripts/unifdef.c:453:28: warning: 'strncpy' output truncated before terminating nul copying 4 bytes from a string of the same length [-Wstringop-truncation] static void Mpass (void) { strncpy(keyword, "if ", 4); Pelif(); } ^~~~~~~~~~~~~~~~~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 # Build took: 0:31:50.638684
