__target_attach_tg_pt_gp() and __target_detach_tg_pt_gp() check if the caller holds lun_tg_pt_gp_lock(). Both functions are static, the callers are acquiring the lock before the invocation of the function so the check looks superfluous. Remove it.
Does this check cause trouble to anyone or to a specific kernel configuration? In other words, do we really need to remove these checks? I think that these checks are useful as documentation to people who read the SCSI target code. The target code is already hard to follow so I think any documentation, especially documentation in the form of code that is checked at runtime, is welcome. Thanks, Bart.
