[Qemu-devel] [PATCH v2 00/12] make dirty-bitmap byte-based |

There are patches floating around to add NBD_CMD_BLOCK_STATUS,
but NBD wants to report status on byte granularity (even if the
reporting will probably be naturally aligned to sectors or even
much higher levels). I've therefore started the task of
converting our block status code to report at a byte granularity
rather than sectors.
This is part two of that conversion: dirty-bitmap. Other parts
include bdrv_is_allocated (at v2 [1]) and replacing
bdrv_get_block_status with a byte based callback in all the
drivers (at v1, needs a rebase [2]).
Available as a tag at:
git fetch git://repo.or.cz/qemu/ericb.git nbd-byte-dirty-v2
No change to the code itself since v1 [3], just tweaking commit
messages and adding John's Reviewed-by tags, and making sure it
still rebases cleanly on top of Max's block branch.

Eric Blake (12):
dirty-bitmap: Report BlockDirtyInfo.count in bytes, as documented
migration: Don't lose errno across aio context changes
dirty-bitmap: Drop unused functions
dirty-bitmap: Track size in bytes
dirty-bitmap: Set iterator start by offset, not sector
dirty-bitmap: Change bdrv_dirty_iter_next() to report byte offset
dirty-bitmap: Change bdrv_get_dirty_count() to report bytes
dirty-bitmap: Change bdrv_get_dirty() to take bytes
dirty-bitmap: Change bdrv_[re]set_dirty_bitmap() to use bytes
mirror: Switch mirror_dirty_init() to byte-based iteration
dirty-bitmap: Switch bdrv_set_dirty() to bytes
dirty-bitmap: Convert internal hbitmap size/granularity
