From 55ef6e7a401fd748b5e879706b02083dc6eb0846 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 16 Dec 2024 08:14:42 +0100 Subject: [PATCH] xfs: hide reserved RT blocks from statfs File systems with a zoned RT device have a large number of reserved blocks that are required for garbage collection, and which can't be filled with user data. Exclude them from the available blocks reported through stat(v)fs. Signed-off-by: Christoph Hellwig Reviewed-by: "Darrick J.
