[Qemu-devel] [PATCH v2 0/4] bitmaps: add inconsistent bit

Posted by John Snow 6 years, 8 months ago

Allow QEMU to read in bitmaps that have the in-use bit set, for the
purposes of allowing users to delete those bitmaps.

This is chosen in preference to a hard error on load to minimize
impact for a non-critical error, but to force the user or management
utility to acknowledge that the bitmap is no longer viable.

Requires: [PATCH v3 00/10] dirty-bitmaps: deprecate @status field

John Snow (4):
  block/dirty-bitmaps: add inconsistent bit
  block/dirty-bitmap: add inconsistent status
  block/dirty-bitmaps: add block_dirty_bitmap_check function
  block/dirty-bitmaps: implement inconsistent bit
