The patch titled
Subject: fs/pipe.c: local vars have to match types of proper pipe_inode_info fields
has been removed from the -mm tree. Its filename was
fs-pipe-local-vars-has-to-match-types-of-proper-pipe_inode_info-fields.patch
This patch was dropped because it was merged into mainline or a subsystem tree

From: Andrei Vagin <avagin@xxxxxxxxx>
Subject: fs/pipe.c: local vars have to match types of proper pipe_inode_info fields
head, tail, ring_size are declared as unsigned int, so all local variables
that operate with these fields have to be unsigned to avoid signed integer
overflow.
Right now, it isn't an issue because the maximum pipe size is limited by
1U<<31.
