Steven Rostedt 98db8df777 ring-buffer: prevent false positive warning ... Impact: eliminate false WARN_ON message If an interrupt goes off after the setting of the local variable tail_page and before incrementing the write index of that page, the interrupt could push the commit forward to the next page. Later a check is made to see if interrupts pushed the buffer around the entire ring buffer by comparing the next page to the last commited page. This can produce a false positive if the interrupt had pushed the commit page forward as stated above. Thanks to Jiaying Zhang for finding this race.
