XFS introduced 64-bit extent counters for inodes via a series of upstream commits and the feature was marked as stable in v6.5 via commit 61d7e8274cd8 (xfs: drop EXPERIMENTAL tag for large extent counts). Further, xfsprogs release v6.5.0 switched this feature on by default in mkfs.xfs via commit e5b18d7d1d96 (mkfs: enable large extent counts by default). Filesystems formatted with large extent count support, nrext64=1, are thus currently not recognizable by GRUB, since this is an incompat feature. Add the required support so that those filesystems and inodes with large extent counters can be read by GRUB.
