# Merge: 447cec034b78 a80712b9cc7e
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Wed Nov 8 09:47:52 2023 -0800

#     Merge tag 'rcu-fixes-v6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks
#     
#     Pull RCU fixes from Frederic Weisbecker:
#     
#      - Fix a lock inversion between scheduler and RCU introduced in
#        v6.2-rc4. The scenario could trigger on any user of RCU_NOCB
#        (mostly Android but also nohz_full)
#     
#      - Fix PF_IDLE semantic changes introduced in v6.6-rc3 breaking
#        some RCU-Tasks and RCU-Tasks-Trace expectations as to what
#        exactly is an idle task. This resulted in potential spurious
#        stalls and warnings.
