Not following... This removes CONFIG_BLK_DEBUG_FS_ZONED and only add this single ifdef here in blk-zoned.c instead of testing the removed config in blk-mq-debugfs.h. Same count and one less config. Sure, there is one ifdef in c code added. But I *really* prefer that instead of having zone related code all over the place guarded with #if defined(CONFIG_BLK_DEV_ZONED). So unless Jens is against this change, I am keeping it. > > Thanks, > > Bart.
