Paul E. McKenney 96017bf903 rcu-tasks: Simplify trc_read_check_handler() atomic operations ... Currently, trc_wait_for_one_reader() atomically increments the trc_n_readers_need_end counter before sending the IPI invoking trc_read_check_handler(). All failure paths out of trc_read_check_handler() and also from the smp_call_function_single() within trc_wait_for_one_reader() must carefully atomically decrement this counter. This is more complex than it needs to be. This commit therefore simplifies things and saves a few lines of code by dispensing with the atomic decrements in favor of having trc_read_check_handler() do the atomic increment only in the success case. In theory, this represents no change in functionality. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>		2021-09-15 11:37:50 -07:00
