nanddump: correct rounding to next page (lead to infinite loop)
The rounding to next page formula was wrong: ex: (len | ~(meminfo->writesize - 1)) + 1; len=128K writesize=4K (len | ~(meminfo->writesize - 1)) + 1 => 4 294 963 201 ?! correct rounding formula: ((len - 1) | (meminfo->writesize - 1)) + 1 => 128K len = 130K ((len - 1) | (meminfo->writesize - 1)) + 1 => 132K modprobe nandsim parts="20,20" badblocks="22,23" without patch: nanddump /dev/mtd1 | wc -c [...] infinite loop with the patch: nanddump /dev/mtd1 | wc -c 327680 Signed-off-by: Richard Genoud <richard.genoud@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
