> Â Â[SCSI] tcm_fc: Adding FC_FC4 provider (tcm_fc) for FCoE target (TCM - target core) support
>
> Â ÂThis is a comprehensive patch for FC-FC4 provider. tcm_fc is a FC-FC4
> Â Âprovider which glues target core (TCM) with Fiber channel library
> Â Â(libfc). tcm_fc uses existing FC4 provider hooks from Fiber channel
> Â Âlibrary. This Fiber channel library is used by FCoE (transport - FC
> Â Âover Ethernet) protocol driver as well.

If CONFIG_TCM_FC=y, this gives:
| drivers/target/tcm_fc/tfc_conf.c:642: warning: âft_initâ defined but not used
Shouldn't the #ifdef MODULE and #endif just be removed?
Who else initializes this module if it's builtin?
E.g. ft_register_configfs() is global, but not used outside this source file?
