After merging the scsi tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

drivers/target/tcm_fc/tfc_io.c:209: warning: format '%x' expects type 'unsigned int', but argument 5 has type 'size_t'

Introduced by commit 3699d92a4d7b ("[SCSI] tcm_fc: Adding FC_FC4 provider
(tcm_fc) for FCoE target (TCM - target core) support").

It appears that this warning was fixed in LIO upstream a while back, but
did not make it into this morning scsi-misc merge. Please apply.

Given that "remaining" really is a length, surely it makes more sense to
print it with %zd than to cast it and print it with %x ...

This is fine with me. Bad habit of explictly casting conversion
specifications from sector_t type usage..

Kiran, would you mind fixing this to use %zd in your tree, and include
this along with the TMR LUN_RESET bugfix for James to include in
scsi-misc..?

Thanks,

No problem. I will fix it and get it out along with my other patch series for offload, big fixes, etc.. via. Open-FCoE which has been rebased to scsi-misc yesterday (scsi-misc now has tcm_fc)

Thanks,
