The issues were found when testing # the ongoing changes introducing atomic consoles and printk kthreads: # # - pr_flush() has to wait for the last reserved record instead of the # last finalized one. Note that records are finalized in random order # when generated by more CPUs in parallel. # # - Ignore non-finalized records during panic(). Messages printed on # panic-CPU are always finalized. Messages printed by other CPUs # might never be finalized when the CPUs get stopped. # # - Block new printk() calls on non-panic CPUs completely. Backtraces # are printed before entering the panic mode. Later messages would # just mess information printed by the panic CPU. # # - Do not take console_lock in console_flush_on_panic() at all. The # original code did try_lock()/console_unlock(). The unlock part # might cause a deadlock when panic() happened in a scheduler code. # # - Fix conversion of 64-bit sequence number for 32-bit atomic # operations" # # * tag 'printk-for-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux: # dump_stack: Do not get cpu_sync for panic CPU # panic: Flush kernel log buffer at the end # printk: Avoid non-panic CPUs writing to ringbuffer # printk: Disable passing console lock owner completely during panic() # printk: ringbuffer: Skip non-finalized records in panic # printk: Wait for all reserved records with pr_flush() # printk: ringbuffer: Cleanup reader terminology # printk: Add this_cpu_in_panic() # printk: For @suppress_panic_printk check for other CPU in panic # printk: ringbuffer: Clarify special lpos values # printk: ringbuffer: Do not skip non-finalized records with prb_next_seq() # printk: Use prb_first_seq() as base for 32bit seq macros # printk: Adjust mapping for 32bit seq macros # printk: nbcon: Relocate 32bit seq macros # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 b0546776ad3f332e215cebc0b063ba4351971cca # make -s -j 160 ARCH=m68k O=/kisskb/build/linus_m5272c3_defconfig_m68k-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/m68k-linux/bin/m68k-linux- m5272c3_defconfig # < make -s -j 160 ARCH=m68k O=/kisskb/build/linus_m5272c3_defconfig_m68k-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/m68k-linux/bin/m68k-linux- help # make -s -j 160 ARCH=m68k O=/kisskb/build/linus_m5272c3_defconfig_m68k-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/m68k-linux/bin/m68k-linux- olddefconfig # make -s -j 160 ARCH=m68k O=/kisskb/build/linus_m5272c3_defconfig_m68k-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/m68k-linux/bin/m68k-linux- /kisskb/src/drivers/tty/serial/mcf.c:473:12: warning: no previous prototype for 'early_mcf_setup' [-Wmissing-prototypes] 473 | int __init early_mcf_setup(struct mcf_platform_uart *platp) | ^~~~~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/linus_m5272c3_defconfig_m68k-gcc13 # Build took: 0:00:43.550210
