Subject: [PATCH] curl: Use _Atomic type to accumulate curl timings
|
|
|
|
Because the global list of times is accessed in parallel by many
|
|
threads, they must be accessed atomically.
|
|
|
|
Fixes: commit 68dddbeb584fb9385915846d259563f74338ffe8
|
|
(cherry picked from commit 4c527063336ccf14d286ef7db5766369e1b23845)
