From 5267f6ef49cb5fba426f2d286817b1355fde31da Mon Sep 17 00:00:00 2001 From: Li Chen Date: Fri, 6 Mar 2026 16:56:39 +0800 Subject: jbd2: add jinode dirty range accessors Provide a helper to fetch jinode dirty ranges in bytes. This lets filesystem callbacks avoid depending on the internal representation, preparing for a later conversion to page units.
