RE: [PATCH v2] ACPI: APEI: do not add task_work to kernel thread to avoid memory leak

I follow and agree with everything up until:

In a conclusion, the error will be handled in a kworker with or without this fix.

Who handles the error if the interrupt happens during the execution of a kthread?

It isn't handled during the interrupt (it can't be).

Can't use the task_work_add() trick to handle it (because this thread never returns to user mode).

So how is the error handled?
