So queue these requests on a list and use a worker to

[PATCH 0/3] virtiofs: Small Cleanups for 5.5
Hi Miklos, Here are few small cleanups for virtiofs for 5.5. I had received some comments from Michael Tsirkin on original virtiofs patches and these cleanups are result of these comments. Thanks Vivek Vivek Goyal (3): virtiofs: Use a common function to send forget virtiofs: Do not send forget request "struct list_head" element virtiofs: Use completions while waiting for queue
