The Linux kernel iSCSI initiator pipelines multiple SCSI commands on the same TCP connection (command queuing). When a write needs R2T for data beyond the immediate portion, collectDataOut may read a pipelined SCSI command instead of the expected Data-Out PDU. Fix: queue non-Data-Out PDUs received during collectDataOut into a pending buffer. The main dispatch loop drains pending PDUs before reading from the connection. This correctly handles interleaved commands during multi-PDU write transfers. Bug found during WSL2 smoke test: mkfs.ext4 hangs at "Writing superblocks" because inode table zeroing sends large writes that exceed FirstBurstLength, triggering R2T while the kernel has already queued the next command.
