It adds spurious traffic, for short. # # On top of it prefetch is notoriously tricky to use for single-threaded # purposes, making it questionable from the get go. # # As such, remove it. # # I admit upfront I did not see value in benchmarking this change, but I # can do it if that is deemed appropriate. # # Removal from new_inode and of the entire thing are in the same patch as # requested by Linus, so whatever weird looks can be directed at that guy. # # Link: https://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git/commit/fs/inode.c?id=c37fa164f793735b32aa3f53154ff1a7659e6442 [1] # Signed-off-by: Mateusz Guzik <mjguzik@gmail.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 c8afaa1b0f8bc93d013ab2ea6b9649958af3f1d3 # make -s -j 40 ARCH=sh O=/kisskb/build/linus_allyesconfig_sh4-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/sh4-linux/bin/sh4-linux- allyesconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # < make -s -j 40 ARCH=sh O=/kisskb/build/linus_allyesconfig_sh4-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 40 ARCH=sh O=/kisskb/build/linus_allyesconfig_sh4-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 40 ARCH=sh O=/kisskb/build/linus_allyesconfig_sh4-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h <stdin>:1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S: Assembler messages: /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:85: Warning: overflow in branch to __restore_all; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:357: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:360: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence {standard input}: Assembler messages: {standard input}: Warning: end of file not at end of a line; newline inserted {standard input}:1096: Error: Missing symbol name in directive {standard input}:1096: Error: unrecognized symbol type "" sh4-linux-gcc: internal compiler error: Segmentation fault signal terminated program cc1 Please submit a full bug report, with preprocessed source (by using -freport-bug).
