+From cda0a857dd7a27cd5d621747464bfe71e8727fff Mon Sep 17 00:00:00 2001
+From: Daniel Kiper <daniel.kiper@oracle.com>
+Date: Tue, 29 May 2018 16:16:02 +0200
+Subject: xfs: Accept filesystem with sparse inodes
+
+The sparse inode metadata format became a mkfs.xfs default in
+xfsprogs-4.16.0, and such filesystems are now rejected by grub as
+containing an incompatible feature.
+
+In essence, this feature allows xfs to allocate inodes into fragmented
+freespace. (Without this feature, if xfs could not allocate contiguous
+space for 64 new inodes, inode creation would fail.)
+
+In practice, the disk format change is restricted to the inode btree,
+which as far as I can tell is not used by grub. If all you're doing
+today is parsing a directory, reading an inode number, and converting
+that inode number to a disk location, then ignoring this feature
+should be fine, so I've added it to XFS_SB_FEAT_INCOMPAT_SUPPORTED
+
+I did some brief testing of this patch by hacking up the regression
+tests to completely fragment freespace on the test xfs filesystem, and
+then write a large-ish number of inodes to consume any existing
+contiguous 64-inode chunk. This way any files the grub tests add and
+traverse would be in such a fragmented inode allocation. Tests passed,
+but I'm not sure how to cleanly integrate that into the test harness.
