The patch titled
cpuset: use seq_*mask_* to print masks
has been removed from the -mm tree. Its filename was
cpuset-use-seq_mask_-to-print-masks.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: cpuset: use seq_*mask_* to print masks
From: Lai Jiangshan <laijs@xxxxxxxxxxxxxx>
1) seq_file excepts that m->count == m->size when it's buf is full,
so current code will causes bugs when buf is overflow.
2) There is not too good that cpuset accesses struct seq_file's
fields directly.
