# Merge: 38814330fedd 7dfb03dd24d4
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Fri Jan 12 16:35:58 2024 -0800
# 
#     Merge tag 'rcu.release.v6.8' of https://github.com/neeraju/linux
#     
#     Pull RCU updates from Neeraj Upadhyay:
#     
#      - Documentation and comment updates
#     
#      - RCU torture, locktorture updates that include cleanups; nolibc init
#        build support for mips, ppc and rv64; testing of mid stall duration
#        scenario and fixing fqs task creation conditions
#     
#      - Misc fixes, most notably restricting usage of RCU CPU stall
#        notifiers, to confine their usage primarily to debug kernels
#     
#      - RCU tasks minor fixes
#     
#      - lockdep annotation fix for NMI-safe accesses, callback
#        advancing/acceleration cleanup and documentation improvements
#     
#     * tag 'rcu.release.v6.8' of https://github.com/neeraju/linux:
#       rcu: Force quiescent states only for ongoing grace period
#       doc: Clarify historical disclaimers in memory-barriers.txt
#       doc: Mention address and data dependencies in rcu_dereference.rst
#       doc: Clarify RCU Tasks reader/updater checklist
#       rculist.h: docs: Fix wrong function summary
#       Documentation: RCU: Remove repeated word in comments
#       srcu: Use try-lock lockdep annotation for NMI-safe access.
#       srcu: Explain why callbacks invocations can't run concurrently
#       srcu: No need to advance/accelerate if no callback enqueued
#       srcu: Remove superfluous callbacks advancing from srcu_gp_start()
#       rcu: Remove unused macros from rcupdate.h
#       rcu: Restrict access to RCU CPU stall notifiers
#       rcu-tasks: Mark RCU Tasks accesses to current->rcu_tasks_idle_cpu
#       rcutorture: Add fqs_holdoff check before fqs_task is created
#       rcutorture: Add mid-sized stall to TREE07
#       rcutorture: add nolibc init support for mips, ppc and rv64
#       locktorture: Increase Hamming distance between call_rcu_chain and rcu_call_chains
