extlinux vs ext4 64 bit
Hi,
It looks like extlinux's code doesn't have support for the "64bit"
feature of ext4:
extlinux:
struct ext2_group_desc {
...
uint32_t bg_inode_table; /* Inodes table block */
...
}
ext4:
struct ext4_group_desc {
...
uint32_t bg_inode_table_lo; /* Inodes table block */
...
uint32_t bg_inode_table_hi; /* Inodes table block MSB */
}
I'm seeing an issue where sometimes the syslinux.cfg my userspace code
is writing is ending up with the high bits set for the block group,
with the symptom that extlinux can't find syslinux....
