The patch titled
openpromfs: factorize out
has been removed from the -mm tree. Its filename is
openpromfs-factorize-out.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: openpromfs: factorize out
From: Jan Engelhardt <jengelh@xxxxxx>
"Move" "common code" out to PTR_NOD, which does the conversion from private
pointer to node number. This is to reduce potential casting/conversion errors
due to redundancy. (The naming PTR_NOD follows PTR_ERR, turning a pointer
into xyz.)
