CONFIG_KCSAN_ASSUME_PLAIN_WRITES_ATOMIC: Assume that plain aligned writes up to word size are atomic

General informations

The Linux kernel configuration item CONFIG_KCSAN_ASSUME_PLAIN_WRITES_ATOMIC:

Help text

Assume that plain aligned writes up to word size are atomic by default, and also not subject to other unsafe compiler optimizations resulting in data races. This will cause KCSAN to not report data races due to conflicts where the only plain accesses are aligned writes up to word size: conflicts between marked reads and plain aligned writes up to word size will not be reported as data races; notice that data races between two conflicting plain aligned writes will also not be reported.
