Use PAGE_SIZE - 1 instead of PAGE_SIZE - 2 when formatting. This patch is dependent on the following two patches. lib/vsprintf: implement bitmap printing through '%*pb[l]' cpumask, nodemask: implement cpumask/nodemask_pr_args() Please wait till the forementioned patches are merged to mainline before applying to subsystem trees.
