Excluded libaio library from mlock may hang system while removing

Bug description:
Hi,
One of our production system hang while executing a custom backup
script, using LVM snapshots and raw copies in order to build an
alternative boot environment.
We opened an issue on the LVM2 Github
(https://github.com/lvmteam/lvm2/issues/159), and one of the
contributor advises us to use at least the LVM2 2.03.17 version, built
with the following patch :
https://github.com/lvmteam/lvm2/commit/a3eb6ba425773224076c41aabc3c490a6a016ee6
The libaio library is, on previous versions, excluded of the mlock
call and it can lead to a full system hang, specifically during a
rootfs snapshot removal, as removing a shapshot freezes the underlying
volume and the system won't be able to read on that volume during this
operation. In rare condtions, this can be harmful if the system
decides to page-out during this operation.
As I understand that it may be complicated to upgrade the LVM2 version
on stable releases of Ubuntu, is it possible to cherry-pick the
relevant (and really simple/small) patch from the LVM2 2.03.17 version
on the current LVM2 versions used by Ubuntu ?
