The patch titled
Subject: lib/bitmap.c: fix documentation for scnprintf() functions
has been removed from the -mm tree. Its filename was
lib-bitmapc-fix-documentation-for-scnprintf-functions.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: lib/bitmap.c: fix documentation for scnprintf() functions
The code comments for bscnl_emit() and bitmap_scnlistprintf() are
describing snprintf() return semantics, but these functions use
scnprintf() return semantics. Fix that, and document the
bitmap_scnprintf() return value as well.
