The XFS filesystem supports a bigtime feature to overcome y2038 problem. This patch makes the GRUB able to support the XFS filesystems with this feature enabled. The XFS counter for the bigtime enabled timestamps starts at 0, which translates to GRUB_INT32_MIN (Dec 31 20:45:52 UTC 1901) in the legacy timestamps. The conversion to Unix timestamps is made before passing the value to other GRUB functions. For this to work properly, GRUB requires an access to flags2 field in the XFS ondisk inode. So, the grub_xfs_inode structure has been updated to cover full ondisk inode.
