# 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:
