These operations were added to co-ordinate filesystem backups/snapshots
for journalling filesystems (especially in conjunction with LVM). At
some point in the future ext3 will also be using them. However, (only
having looked at preliminary patches, and not the final 2.4.1-pre reiserfs
merge) it is bad to insert them in the middle of the super_operations
struct at this point, as it breaks every filesystem that isn't part of
the kernel. That said, the addition of (reiserfs-specific) read_inode2
and dirty_inode pointers also break all non-kernel filesystems. Argh!
Cheers, Andreas
