| * | bitmap: add atomic set functions | Stefan Hajnoczi | 2015-06-05 | 1 | -0/+38 |
| | | | | | | | | | | | | | | | | | | | Use atomic_or() for atomic bitmaps where several threads may set bits at the same time. This avoids the race condition between threads loading an element, bitwise ORing, and then storing the element. When setting all bits in a word we can avoid atomic ops and instead just use an smp_mb() at the end. Most bitmap users don't need atomicity so introduce new functions.

| * | bitmap: use long as index | Juan Quintela | 2014-01-13 | 1 | -30/+30 |
| | | | | | | | | | | | Move index and size fields from int to long. We need that for migration. long is 64 bits on sane architectures, and 32bits should be enough on all the 32bits architectures.
