Source: qemu Followup-For: Bug #1030545 For anyone else looking into this bug: it seemed to me that 'qcow2.c' is a likely candidate for this infinite looping[1] behaviour to originate from.
The fact that metadata preallocation is enabled when it occurs could be relevant information too. (my guess is that it is _not_ a kernel-related regression, but I could be wrong about that) [1] - https://gitlab.com/qemu-project/qemu/-/blob/v7.2.0/block.c#L574-576
