btrfs: increase output size for LOGICAL_INO_V2 ioctl Build-server workloads have hundreds of references per file after dedup. Multiply by a few snapshots and we quickly exhaust the limit of 2730 references per extent that can fit into a 64K buffer. Raise the limit to 16M to be consistent with other btrfs ioctls (e.g. TREE_SEARCH_V2, FILE_EXTENT_SAME). To minimize surprising userspace behavior, apply this change only to the LOGICAL_INO_V2 ioctl.
