This happens with kernels older than 6.12, where the memory.peak reset feature was introduced.

This happens with kernels older than 6.12, where the memory.peak reset feature was introduced.

You're absolutely correct regarding the kernel version limitation. We have identified two root causes for this invalid argument error:
The file-descriptor-scoped memory.peak reset functionality is fully stabilized and officially available starting from Linux 6.12 (ref: https://kernelnewbies.org/Linux_6.12). On kernels 6.1 ~ 6.11, memory.peak remains read-only, and any write operation will fail with EINVAL.
Our former implementation wrote non-empty content to reset the peak value, which does not conform to kernel specs and would also fail even on compatible kernels.
This PR #2724 resolves both issues thoroughly:
Implements precise kernel version parsing and detection, enabling memory peak reset only on kernels >= 6.12, and silently skipping reset logic on older kernels to eliminate redundant error logs.
Fixes the write logic to use standard zero-length writes that strictly match upstream kernel semantics.
Supplements comprehensive unit tests and integration tests covering various kernel version naming formats and edge cases, guaranteeing consistent behavior across different environments.
Feel free to take a review, all feedback and suggestions are highly welcome!
