.SH NAME
splice \- splice data to/from a pipe
.SH SYNOPSIS
@ -88,6 +88,12 @@ This is only a hint to the kernel:
pages may still be copied if the kernel cannot move the
pages from the pipe, or if
the pipe buffers don't refer to full pages.
The initial implementation of this flag was buggy:
therefore starting in Linux 2.6.21 it is a no-op
(but is still permitted in a
.BR splice ()
call);
in the future, a correct implementation may be restored.
