Steven Rostedt 62f0b3eb5c ring-buffer: check for swapped buffers in start of committing ...

Because the irqsoff tracer can swap an internal CPU buffer, it is possible
that a swap happens between the start of the write and before the committing
bit is set (the committing bit will disable swapping).

This patch adds a check for this and will fail the write if it detects it.
