The patch titled
Subject: ipc: fix potential oops when src msg > 4k w/ MSG_COPY
has been removed from the -mm tree. Its filename was
ipc-fix-potential-oops-when-src-msg-4k-w-msg_copy.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Peter Hurley <[email protected]>
Subject: ipc: fix potential oops when src msg > 4k w/ MSG_COPY
If the src msg is > 4k, then dest->next points to the
next allocated segment; resetting it just prior to dereferencing
is bad.
