srcu: Make Tiny SRCU able to operate in preemptible kernels
srcu: Define SRCU_READ_FLAVOR_ALL in terms of symbols
srcu: Use ->srcu_gp_seq for rcutorture reader batch
srcu: Pull ->srcu_{un,}lock_count into a new srcu_ctr structure
srcu: Make SRCU readers use ->srcu_ctrs for counter selection
srcu: Make Tree SRCU updates independent of ->srcu_idx
srcu: Force synchronization for srcu_get_delay()
srcu: Rename srcu_check_read_flavor_lite() to
srcu_check_read_flavor_force()
srcu: Add SRCU_READ_FLAVOR_SLOWGP to flag need for synchronize_rcu()
srcu: Pull pointer-to-integer conversion into __srcu_ptr_to_ctr()
srcu: Pull integer-to-pointer conversion into __srcu_ctr_to_ptr()
srcu: Move SRCU Tree/Tiny definitions from srcu.h
srcu: Add SRCU-fast readers
rcutorture: Add ability to test srcu_read_{,un}lock_fast()
refscale: Add srcu_read_lock_fast() support using "srcu-fast"
rcutorture: Make scenario SRCU-P use srcu_read_lock_fast()
srcu: Fix srcu_read_unlock_{lite,nmisafe}() kernel-doc
srcu: Document that srcu_{read_lock,down_read}() can share srcu_struct
srcu: Add srcu_down_read_fast() and srcu_up_read_fast()
srcu: Make SRCU-fast also be NMI-safe
