This can prevent applications like WINE from failing on read or write operation on a previously locked file region from the same netfd from another process if we use mandatory brlock style. It is actual for WINE because during a run of WINE program two processes work on the same netfd - share the same file struct between several VFS fds: 1) WINE-server does open and lock; 2) WINE-application does read and write.
