From 3a97d267fd91214d4a0da953b129c877587967ef Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 30 Apr 2025 14:26:51 -0700 Subject: [PATCH] xfs: require XFS_SB_FEAT_INCOMPAT_LOG_XATTRS for attr log intent item recovery [ Upstream commit 8ef1d96a985e4dc07ffbd71bd7fc5604a80cc644 ] The XFS_SB_FEAT_INCOMPAT_LOG_XATTRS feature bit protects a filesystem from old kernels that do not know how to recover extended attribute log intent items. Make this check mandatory instead of a debugging assert. Fixes: fd920008784ea ("xfs: Set up infrastructure for log attribute replay") Signed-off-by: Darrick J.
