Subject: [PATCH] cpusets: remove bitmap_scnprintf_len and cpumask_scnprintf_len
From: Paul Jackson <pj@....com>
Remove bitmap_scnprintf_len and cpumask_scnprintf_len.
They aren't used. They were briefly used as part of some
other patches to provide an alternative format for displaying
some /proc and /sys cpumasks. They probably should have been
removed when those other patches were dropped, in favor of a
different solution.
