Please consider this patch series for the next merge window. Thanks, Bart. Changes compared to v3: - Changed the 'present' counter from 8 to 32 bits. - Fixed a bug in an error path (reported by John Garry). - Changed EXPORT_SYMBOL() into EXPORT_SYMBOL_GPL(). - Split patch 1/3 into two patches. Changes compared to v2: - Optimized the show_info == NULL case. - Added a patch that removes the code that clears the module pointer in the host template. Changes compared to v1: - Fix the CONFIG_SCSI_PROC_FS=n build.
