Subject: [GIT PULL] Fix rcu_torture_read ftrace event

Hello, Linus,

This post-merge-window urgent pull request brings the rcu_torture_read
event trace into line with the new trace tools.  Without this commit,
users of those tools perceive a regression.

Just in case there is confusion, the plan is still for Joel Fernandes
and Boqun Feng to send the RCU pull request into the v6.4 merge window.
I will be doing my other pull requests for v6.4, and I will also be
handling the RCU pull request for the v6.5 merge window.

The following changes since commit fe15c26ee26efa11741a7b632e9f23b01aca4cc6:

  Linux 6.3-rc1 (2023-03-05 14:52:03 -0800)

are available in the Git repository at:

  rcu: Fix rcu_torture_read ftrace event (2023-03-22 14:05:24 -0700)

----------------------------------------------------------------
Urgent RCU pull request for v6.3

This commit brings the rcu_torture_read event trace into line with
the new trace tools by replacing this event trace's __field() with the
corresponding __array().  Without this commit, the new trace tools will
fail when presented wtih an rcu_torture_read event trace, which is a
regression from the viewpoint of trace tools users.
