File locking should all work, in linux 99% of it is in the vfs code,
all the filesystem gets to be involved in is maintaining the fact
that mandatory locks are present on the inode. I think.

Now you might discover some scaling issues in the linux file locking
implementation, but that is a generic linux issue, not an xfs one.
Some attempts have been made at making it scale better.
