Hi Nic, here's a set of patches and fixes I've found during debugging FCoE over virtio. The first two fix a race condition I've encountered during starting and stopping initiators; they are similar to your prior patches, but I still think they should be applied to avoid any race issues. The next three are just minor cleanups, but the last one is _absolutely_ crucial. With the current code tcm_fc will behave _very_ odd if you're running in a virtualized environment, as the xid allocator in libfc will be thouroughly thrashed by sending frames on _other_ cpus than those the originator frame got received on. This causes frames to be delayed (by up to several minutes) leading to I/O errors on the initiator side.
As usual, comments and reviews are welcome.
