Previous commit uses wrong clock id and forget to release an additional rdlock. cc @Eric977 Sorry for missing this in my initial review. Fixes https://github.com/llvm/llvm-project/issues/100960. Notice that the timestamp is created via ```c++ LIBC_NAMESPACE::clock_gettime(CLOCK_REALTIME, &ts); ts.tv_nsec += 50'000; if (ts.tv_nsec >= 1'000'000'000) { ts.tv_nsec -= 1'000'000'000; ts.tv_sec += 1; } ```
