-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.
