The patch titled Subject: mm: fix off-by-one bug in print_nodes_state() has been removed from the -mm tree. Its filename was mm-fix-off-by-one-bug-in-print_nodes_state.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/ ------------------------------------------------------ From: Ryota Ozaki <ozaki.ryota@xxxxxxxxx> Subject: mm: fix off-by-one bug in print_nodes_state() /sys/devices/system/node/{online,possible} outputs a garbage byte because print_nodes_state() returns content size + 1. To fix the bug, the patch changes the use of cpuset_sprintf_cpulist to follow the use at other places, which is clearer and safer. This bug was introduced since v2.6.24 (bde631a51876f23e9).
