Yes, but that's not new to 2.6.18.  However, there *are* some changes
to linux/fs.h that affect OpenAFS (but don't actually break the build,
even though they perhaps should).  Specifically:

- struct super_operations.statfs now takes a struct dentry * rather
  than a struct super_block * as its first argument.

- struct file_system_type.get_sb takes an additional struct vfsmount *
  argument and returns int rather than struct super_block *.

I think either change alone would account for the lossage reported in
this thread.

In addition, struct file_operations.flush has gained a (final)
fl_owner_t argument, though C's calling conventions should make that
particular change harmless.

Thanks for inspiring me to take a closer look!
