Linus, please pull the latest printk changes from
git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk tags/printk-for-4.18 There will be conflicts in lib/vsprintf.c that are caused by late fixes for 4.17. The proposed resolution can be found in the branch git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk.git for-4.18-vsprintf-conflict Also I am sorry that I have rebased today. I added one late ack and removed one fix that was not good enough. I found a race in that fix when writing this summary. ============== - Help userspace log daemons to catch up with a flood of messages. They will get waken after each message even if the console is far behind and handled by another process. - Flush printk safe buffers safely even when panic() happens in the normal context. - Fix possible va_list reuse when race happened in printk_safe(). - Remove %pCr printf format to prevent sleeping in the atomic context. - Misc vsprintf code cleanup. ---------------------------------------------------------------- Andy Shevchenko (7): lib/test_printf: Mark big constant with UL lib/vsprintf: Make dec_spec global lib/vsprintf: Make strspec global lib/vsprintf: Make flag_spec global lib/vsprintf: Move pointer_string() upper lib/vsprintf: Deduplicate pointer_string() lib/vsprintf: Mark expected switch fall-through Geert Uytterhoeven (4): clk: renesas: cpg-mssr: Stop using printk format %pCr thermal: bcm2835: Stop using printk format %pCr serial: sh-sci: Stop using printk format %pCr lib/vsprintf: Remove atomic-unsafe support for %pCr Petr Mladek (2): Merge branch 'for-4.18-vsprintf-cleanup' into for-4.18 Merge branch 'for-4.18-vsprintf-pcr-removal' into for-4.18 Sergey Senozhatsky (3): vsprintf: Tweak pF/pf comment printk: wake up klogd in vprintk_emit printk: drop in_nmi check from printk_safe_flush_on_panic() Shunyong Yang (1): lib/vsprintf: Replace space with '_' before crng is ready Tetsuo Handa (1): printk: fix possible reuse of va_list variable Documentation/core-api/printk-formats.rst | 3 +- drivers/clk/renesas/renesas-cpg-mssr.c | 9 +- drivers/thermal/broadcom/bcm2835_thermal.c | 4 +- drivers/tty/serial/sh-sci.c | 4 +- kernel/printk/printk.c | 14 +-- kernel/printk/printk_safe.c | 7 +- lib/test_printf.c | 2 +- lib/vsprintf.c | 133 ++++++++++++----------------- 8 files changed, 71 insertions(+), 105 deletions(-)
