| H A D | dirty-bitmap.h | 3b5d4df0 Mon Sep 25 14:55:19 GMT 2017 Eric Blake <eblake@redhat.com> dirty-bitmap: Change bdrv_get_dirty_locked() to take bytes
Half the callers were already scaling bytes to sectors; the other
half can eventually be simplified to use byte iteration. Both
callers were already using the result as a bool, so make that
explicit. Making the change also makes it easier for a future
dirty-bitmap patch to offload scaling over to the internal hbitmap.
Remember, asking whether a byte is dirty is effectively asking
whether the entire granularity containing the byte is dirty, since
we only track dirtiness by granularity.
