4b060420a Mike Travis 2011-05-24 653 * then it must be terminated with a \0.
4b060420a Mike Travis 2011-05-24 654 * @is_user: location of buffer, 0 indicates kernel space

^1da177e4 Linus Torvalds 2005-04-16 658 * Input format is a comma-separated list of decimal numbers and

^1da177e4 Linus Torvalds 2005-04-16 660 * decimal numbers, the smallest and largest bit numbers set in

2d13e6ca4 Noam Camus 2016-10-11 662 * Optionally each range can be postfixed to denote that only parts of it
2d13e6ca4 Noam Camus 2016-10-11 663 * should be set. The range will divided to groups of specific size.
2d13e6ca4 Noam Camus 2016-10-11 664 * From each group will be used only defined amount of bits.
