Hi, Here is the 12th version of improvement patches for making persistent ring buffers robust to failures. The previous version is here: https://lore.kernel.org/all/177391152793.193994.8986943289250629418.stgit@mhiramat.tok.corp.google.com/ (local) In this version, I rebased it on tracing/fixes branch (thus the first fix patch has been removed) and fixed a build error which came from a copy-paste mistake. Thank you, --- Masami Hiramatsu (Google) (4): ring-buffer: Flush and stop persistent ring buffer on panic ring-buffer: Skip invalid sub-buffers when validating persistent ring buffer ring-buffer: Skip invalid sub-buffers when rewinding persistent ring buffer ring-buffer: Add persistent ring buffer selftest arch/alpha/include/asm/Kbuild | 1 arch/arc/include/asm/Kbuild | 1 arch/arm/include/asm/Kbuild | 1 arch/arm64/include/asm/ring_buffer.h | 10 + arch/csky/include/asm/Kbuild | 1 arch/hexagon/include/asm/Kbuild | 1 arch/loongarch/include/asm/Kbuild | 1 arch/m68k/include/asm/Kbuild | 1 arch/microblaze/include/asm/Kbuild | 1 arch/mips/include/asm/Kbuild | 1 arch/nios2/include/asm/Kbuild | 1 arch/openrisc/include/asm/Kbuild | 1 arch/parisc/include/asm/Kbuild | 1 arch/powerpc/include/asm/Kbuild | 1 arch/riscv/include/asm/Kbuild | 1 arch/s390/include/asm/Kbuild | 1 arch/sh/include/asm/Kbuild | 1 arch/sparc/include/asm/Kbuild | 1 arch/um/include/asm/Kbuild | 1 arch/x86/include/asm/Kbuild | 1 arch/xtensa/include/asm/Kbuild | 1 include/asm-generic/ring_buffer.h | 13 ++ include/linux/ring_buffer.h | 1 kernel/trace/Kconfig | 15 ++ kernel/trace/ring_buffer.c | 237 ++++++++++++++++++++++++++-------- kernel/trace/trace.c | 4 + 26 files changed, 241 insertions(+), 59 deletions(-) create mode 100644 arch/arm64/include/asm/ring_buffer.h create mode 100644 include/asm-generic/ring_buffer.h -- Masami Hiramatsu (Google) [off-list ref]
