[PATCH v2 00/10] usb/msd: Permit relaxed ordering of IN packets

[Nicholas Piggin <npiggin@gmail.com>]

This series ultimately permits relaxed ordering of USB mass-storage
packets from the host, as allowed by the usbmassbulk 1.0 spec, but
not usually seen in drivers. AIX drivers do require this ordering.

Since v1:

https://lore.kernel.org/qemu-devel/20241212091323.1442995-1-npiggin@gmail.com/

- Rebased on upstream with one patch from the series merged.
- Fixed a few build warnings on 32-bit hosts.

Thanks,
Nick
