[PATCH] [221/223] Un-inline get_pipe_info() helper function

From: Andi Kleen
Date: Sun Dec 12 2010 - 18:49:31 EST


2.6.35-longterm review patch. If anyone has any objections, please let me know.

------------------
From: Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx>

commit 72083646528d4887b920deb71b37e09bc7d227bb upstream.

This avoids some include-file hell, and the function isn't really
important enough to be inlined anyway.
