And the fact that even the kernel VM # maintainers apparently didn't catch that this "fix" is not a fix any # more pretty much proves the point that people can't be expected to # understand the implications of the question. # # It may well be the case that we could improve things further, and that # __thp_get_unmapped_area() should take the mapping randomization into # account even for 64-bit kernels. Maybe we should not be so eager to use # THP mappings. # # But in no case should this be a kernel config option. # # Cc: Rafael Aquini <aquini@redhat.com> # Cc: Andrew Morton <akpm@linux-foundation.org> # Cc: Jiri Slaby <jirislaby@kernel.org> # Cc: Suren Baghdasaryan <surenb@google.com> # Cc: Matthew Wilcox (Oracle) <willy@infradead.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 14d7c92f8df9c0964ae6f8b813c1b3ac38120825 # make -s -j 24 ARCH=um O=/kisskb/build/linus_defconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 defconfig # < make -s -j 24 ARCH=um O=/kisskb/build/linus_defconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 help # make -s -j 24 ARCH=um O=/kisskb/build/linus_defconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 olddefconfig # make -s -j 24 ARCH=um O=/kisskb/build/linus_defconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 LINK linux Completed OK # rm -rf /kisskb/build/linus_defconfig_um-x86_64-gcc12 # Build took: 0:01:41.085800
