fs locks: export informational name

Hi,

I'm currently rewritting lslk(8) from scratch so we can integrate it in
util-linux, and continue maintaining it.

In order to not break userspace, the kernel is currently exporting the
major:minor numbers of the device where the locked file resides. Could
we agree on defining WE_CAN_BREAK_LSLK_NOW and start exporting the
informational name instead?

Thanks,
Davidlohr
