My apologies if I missed it, but this looks like the most recent version of this patch ([PATCH] Btrfs-progs: add support for mixed data+metadata block groups V3), and this version needs updating to take into account that BTRFS_FEATURE_INCOMPAT_SPACE_CACHE is no longer needed.
The kernel btrfs code expects: #define BTRFS_FEATURE_INCOMPAT_MIXED_GROUPS (1ULL << 2) But this version of the patch gives: #define BTRFS_FEATURE_INCOMPAT_MIXED_GROUPS (1ULL << 3) with (1ULL << 2) being occupied by the space_cache incompat flag. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
