Merge tag 'trace-v5.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt...

Pull tracing fixes from Steven Rostedt:
 "Fixes to previous fixes.

  Unfortunately, the last set of fixes introduced some minor bugs:

   - The bootconfig apply_xbc() leak fix caused the application to
     return a positive number on success, when it should have returned
     zero.

   - The preempt_irq_delay_thread fix to make the creation code wait for
     the kthread to finish to prevent it from executing after module
     unload, can now cause the kthread to exit before it even executes
     (preventing it to run its tests).

   - The fix to the bootconfig that fixed the initrd to remove the
     bootconfig from causing the kernel to panic, now prints a warning
     that the bootconfig is not found, even when bootconfig is not on
     the command line"
