SPLICE_F_MOVE

SPLICE_F_MOVE

[Remi Machet]

Hi,

Does anyone know if SPLICE_F_MOVE is obsolete or still in use ?

The documentation says that the flag should be used to tell splice not
to copy the data when moving data to/from a pipe, but I cannot find
anywhere in the kernel where this flag is being used or checked for.

Thanks,

Remi

It's not currently used, it got yanked and is waiting for a replacement
implementation.
