From 68db60bf01c131c09bbe35adf43bd957a4c124bc Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Mon, 16 Oct 2023 09:34:39 -0700 Subject: xfs: create a helper to compute leftovers of realtime extents Create a helper to compute the misalignment between a file extent (xfs_extlen_t) and a realtime extent.
