[PATCH v5 0/1] qcow2: add a way to repair bitmaps

Posted by Jean-Louis Dupond 1 month, 4 weeks ago

A v5 (and hopefully final :)) version of the patch.

The only change since v4 is that QSIMPLEQ_FOREACH is replaced by QSIMPLEQ_FOREACH_SAFE.
This to avoid a use after free when we free the 'bm' in the loop.

Thanks
Jean-Louis
