Subject: [PATCH net-next v2 0/3] vsock: SOCK_LINGER rework

Change vsock's lingerning to wait on close() until all data is sent, i.e.
until workers picked all the packets for processing.

Changes in v2:
- Comment that some transports do not implement unsent_bytes [Stefano]
- Reduce the indentation of virtio_transport_wait_close() [Stefano] 
- Do not linger on shutdown(), expand the commit messages [Paolo]
- Link to v1: https://lore.kernel.org/r/20250407-vsock-linger-v1-0-1458038e3492@rbox.co

Changes in v1:
- Do not assume `unsent_bytes()` is implemented by all transports [Stefano]
- Link to v0: https://lore.kernel.org/netdev/df2d51fd-03e7-477f-8aea-938446f47864@rbox.co/
