#     Merge tag 'printk-for-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
#     
#     Pull printk updates from Petr Mladek:
#      "Improve the behavior during panic. 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"
