btrfs: use standard debug config option to enable free-space-cache debug prints (1afb648e) · Commits · 戴 / test

free-space-cache.c has it's own set of DEBUG ifdefs which need to be turned on instead of the global CONFIG_BTRFS_DEBUG to print debug messages about failed block-group writes. Switch this over to CONFIG_BTRFS_DEBUG so we always see these messages when running a debug kernel. Reviewed-by:
