[pve-devel] [RFC guest-common 4/4] guest helpers: add helper to overrule active tasks of a specific type

[Wolfgang Bumiller]

Patch itself LGTM, just a note on sending patch series in general:

If you number patches throughout a whole series rather than the
individual repositories (as in, this one is labeled 4/4 instead of 1/1),
it would be nice if the order also helps determine dependencies.

Since the sub introduced here is used in 2/4 and 3/4, it doesn't make
sense for this to come last.
`qemu-server` and `container` will both want their guest-common
dependency bumped to the version which includes this patch.
