- * offset down to make it relative to the stripe instead of the lov.
- *
- * the harder case is what to do when the offset doesn't intersect the
- * stripe. callers will want start offsets clamped ahead to the start
- * of the nearest stripe in the file. end offsets similarly clamped to the
- * nearest ending byte of a stripe in the file:
- *
- * all this function does is move offsets to the nearest region of the
- * stripe, and it does its work "mod" the full length of all the stripes.
- * consider a file with 3 stripes:
- *
- * S E
- * ---------------------------------------------------------------------
- * | 0 | 1 | 2 | 0 | 1 | 2 |
- * ---------------------------------------------------------------------
- *
- * to find stripe 1's offsets for S and E, it divides by the full stripe
- * width and does its math in the context of a single set of stripes:
- *
- * S E
- * -----------------------------------
- * | 0 | 1 | 2 |
- * -----------------------------------
- *
- * it'll notice that E is outside stripe 1 and clamp it to the end of the
- * stripe, then multiply it back out by lov_off to give the real offsets in
- * the stripe:
- *
- * S E
- * ---------------------------------------------------------------------
- * | 1 | 1 | 1 | 1 | 1 | 1 |
- * ---------------------------------------------------------------------
- *
- * it would have done similarly and pulled S forward to the start of a 1
- * stripe if, say, S had landed in a 0 stripe.
- *
- * this rounding isn't always correct. consider an E lov offset that lands
- * on a 0 stripe, the "mod stripe width" math will pull it forward to the
- * start of a 1 stripe, when in fact it wanted to be rounded back to the end
- * of a previous 1 stripe. this logic is handled by callers and this is why:
- *
- * this function returns < 0 when the offset was "before" the stripe and
- * was moved forward to the start of the stripe in question; 0 when it
- * falls in the stripe and no shifting was done; > 0 when the offset
- * was outside the stripe and was pulled back to its final byte. */
