Hi Pavel,

VFS already has some sort of this capability - now it's done through flock/LOCK_MAND mechanis, but that approach is non-atomic. This patchset build new capabilities on top of the existing one but doesn't bring any changes into the flock call semantic.

This has probably been discussed, but is Linux's leases implementation
not sufficient?  Just wondering.
