pub fn walk_memfd_create<P: PhysicalMemoryProvider>(
reader: &ObjectReader<P>,
) -> Result<Vec<MemfdInfo>>Expand description
Walk the task list and collect information about open memfd_create file descriptors.
For each process, walks mm_struct.mmap (the VMA chain). For every VMA
that is file-backed, the dentry name is read; if it starts with "memfd:"
the mapping is recorded.
Gracefully returns Ok(vec![]) if any required kernel symbol is absent,
so callers on unexpected kernel versions are not broken.
