Hello Everyone,
A while ago Kevin noticed that the replication driver doesn't properly attach
the children it wants to use. Instead, it directly copies the BdrvChilds from
it's backing file, which is wrong. Ths Patchset fixes the problem, fixes a
potential crash in replication_co_writev due to missing permissions and removes
a workaround that was put in place back then.
Regards,
Lukas Straub
Changes:
-v4:
