From 7eed40a07c59e9cf2e66eafd70ac65ad4fc14a7c Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 12 Dec 2018 15:18:52 -0800 Subject: [PATCH] xfs: require both realtime inodes to mount [ Upstream commit 64bafd2f1e484e27071e7584642005d56516cb77 ] Since mkfs always formats the filesystem with the realtime bitmap and summary inodes immediately after the root directory, we should expect that both of them are present and loadable, even if there isn't a realtime volume attached. There's no reason to skip this if rbmino == NULLFSINO; in fact, this causes an immediate crash if the there /is/ a realtime volume and someone writes to it. Signed-off-by: Darrick J.
