Sorry... I missed copy maintainers and qemu-stable. This should be
considered a regression.

Subject: [PATCH] virtio-blk: Fix clean up of host notifiers for single
MR transaction.
To: <qemu-devel@nongnu.org>


The code that introduced "virtio-blk: Configure all host notifiers in
a single MR transaction" introduced a second loop variable to perform
cleanup in second loop, but mistakenly still refers to the first
loop variable within the second loop body.

Fixes: d0267da61489 ("virtio-blk: Configure all host notifiers in a
single MR transaction")
