From 6b08901a6e8fcda555f3ad39abd73bb0dd37f231 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 20 Nov 2024 16:20:27 -0800 Subject: xfs: add realtime reverse map inode to metadata directory Add a metadir path to select the realtime rmap btree inode and load it at mount time. The rtrmapbt inode will have a unique extent format code, which means that we also have to update the inode validation and flush routines to look for it. Signed-off-by: "Darrick J.
