# Merge: b2f02e9cdaad ce13389053a3
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'rcu.2022.05.19a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu
#     
#     Pull RCU update from Paul McKenney:
#     
#      - Documentation updates
#     
#      - Miscellaneous fixes
#     
#      - Callback-offloading updates, mainly simplifications
#     
#      - RCU-tasks updates, including some -rt fixups, handling of systems
#        with sparse CPU numbering, and a fix for a boot-time race-condition
#        failure
#     
#      - Put SRCU on a memory diet in order to reduce the size of the
#        srcu_struct structure
#     
#      - Torture-test updates fixing some bugs in tests and closing some
#        testing holes
#     
#      - Torture-test updates for the RCU tasks flavors, most notably ensuring
#        that building rcutorture and friends does not change the
#        RCU-tasks-related Kconfig options
#     
#      - Torture-test scripting updates
#     
#      - Expedited grace-period updates, most notably providing
#        milliseconds-scale (not all that) soft real-time response from
#        synchronize_rcu_expedited().
#     
#        This is also the first time in almost 30 years of RCU that someone
#        other than me has pushed for a reduction in the RCU CPU stall-warning
#        timeout, in this case by more than three orders of magnitude from 21
#        seconds to 20 milliseconds. This tighter timeout applies only to
#        expedited grace periods
#
