From be49fa968f98cf797b16aa279b11c431199b3af3 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Tue, 14 Nov 2023 10:39:26 +0100 Subject: [PATCH] xfs: allow userspace to rebuild metadata structures Source kernel commit: 5c83df2e54b6af870e3e02ccd2a8ecd54e36668c Add a new (superuser-only) flag to the online metadata repair ioctl to force it to rebuild structures, even if they're not broken. We will use this to move metadata structures out of the way during a free space defragmentation operation. Signed-off-by: Darrick J.
