virt: vbox: Do not use wait_event_interruptible when called from kernel context

2021-01-27T13:37:02+00:00

Do not use wait_event_interruptible when vbg_hgcm_call() gets called from kernel-context, such as it being called by the vboxsf filesystem code. This fixes some filesystem related system calls on shared folders unexpectedly failing with -EINTR.
