Which means the bug is in xfs_bmap_add_attrfork_local() in calling
xfs_bmap_local_to_extents(). i.e it assumes that the local data is
either directory data or extent data, and is attaching extent tree
verifiers to the buffer that contains a remote symlink. Thinking
time now needed, as this affects the symlink CRC changes as well.
Thanks for the debug help, Lukas.
Cheers,
Dave.
