• reduce pipe->mutex contention by pre-allocating outside the lock (lore.kernel.org/linux-fsdevel/20260524-fix_pip…) — While profiling Meta's caching code, I found pipe->mutex contention on the hot path. anonpipewrite() currently calls allocpage() once per page while holding pipe->mutex. The allocation can sleep doing direct reclaim and runs memcg charging, which extends the critical section and stalls any concurrent reader on the same mutex.
