Wong" Date: Mon, 12 Feb 2024 15:18:20 +0100 Subject: [PATCH] xfs: create a helper to convert rtextents to rtblocks Source kernel commit: fa5a387230861116c2434c20d29fc4b3fd077d24 Create a helper to convert a realtime extent to a realtime block. Later on we'll change the helper to use bit shifts when possible. Signed-off-by: Darrick J.
