The original code which handles the recovery of a RAID 6 disks array assumes that all reads are multiple of 1 << GRUB_DISK_SECTOR_BITS and it assumes that all the I/O is done via the struct grub_diskfilter_segment. This is not true for the btrfs code. In order to reuse the native grub_raid6_recover() code, it is modified to not call grub_diskfilter_read_node() directly, but to call an handler passed as an argument.
