In netuse.lists.linux-kernel you write:

For certain applications (multiple concurrent accesses on very
large files as generated by database applications) it can be
desireable to support finer grained locks than on inode level.
Such locks would allow for concurrent writes into the same file
iff these writes do not overlap.

Silicon Graphics XFS does this.
