  "message": "block: Fix overrun in lcm() and move it to lib\n\nlcm() was defined to take integer-sized arguments.  The supplied\narguments are multiplied, however, causing us to overflow given\nsufficiently large input.  That in turn led to incorrect optimal I/O\nsize reporting in some cases (RAID over RAID).\n\nSwitch lcm() over to unsigned long similar to gcd() and move the\nfunction from blk-settings.c to lib.\n\nSigned-off-by: Martin K.
