We have a patch under review which does in fact make use of the

Hi,
We are pleased to announce the call for presentations for this years
Confidential Computing MC at the Linux Plumbers Conference.
In this microconference we want to discuss ongoing developments around
Linux support for memory encryption and support for confidential

If we repeatedly fail to fake offline memory to unplug it, we won't be
sending any unplug requests to the device. However, we only check if the
config changed when sending such (un)plug requests.
We could end up trying for a long time to unplug memory, even though
the config changed already and we
Just like we do with alloc_contig_range(), let's convert all unknown
errors to -EBUSY, but WARN so we can look into the issue. For example,
offline_pages() could fail with -EINTR, which would be unexpected in our
case.

In case offline_and_remove_memory() fails in SBM, we leave a completely
unplugged Linux memory block stick around until we try plugging memory
again. We won't try removing that memory block again.
offline_and_remove_memory() may, for example, fail if we're racing with
another alloc_contig_range()
Some cleanups+optimizations primarily around offline_and_remove_memory().
Patch #1 drops the "unsafe unplug" feature where we might get stuck in
offline_and_remove_memory() forever.
Patch #2 handles unexpected errors from offline_and_remove_memory() a bit
nicer.
Patch #3 handles the case where o
When "unsafe unplug" is enabled, we don't fake-offline all memory ahead of
actual memory offlining using alloc_contig_range(). Instead, we rely on
offline_pages() to also perform actual page migration, which might fail
or take a very long time.
In that case, it's possible to easily run into endles

This is just poking holes into the abstraction..
