btrfs: btrfs_debug should consume fs_info when DEBUG is not defined
We can hit unused variable warnings when btrfs_debug and friends are just aliases for no_printk. This is due to the fs_info not getting consumed by the function call, which can happen if convenenience variables are used. This patch adds a new btrfs_no_printk static inline that consumes the convenience variable and does nothing else. It silences the unused variable warning and has no impact on the generated code: $ size fs/btrfs/extent_io.o* text data bss dec hex filename 44072 152 32 44256 ace0 fs/btrfs/extent_io.o.btrfs_no_printk 44072 152 32 44256 ace0 fs/btrfs/extent_io.o.no_printk Fixes: 27a0dd61 (Btrfs: make btrfs_debug match pr_debug handling related to DEBUG) Signed-off-by:Jeff Mahoney <jeffm@suse.com> Signed-off-by:
