Subject: mm/rmap: update mm/interval_tree.c comments
Date: Fri, 10 Jul 2026 21:16:46 +0100

Update the file comment to clarify that both file-backed and anonymous
interval trees are provided, referencing the relevant data types for
clarity.

Also add comments to indicate which parts of the file apply to each.

While we're here, convert the VM_BUG_ON_VMA() to VM_WARN_ON_ONCE_VMA().
