[PATCH] btrfs: Remove impossible BUG_ON in get_tree_block_key

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



relocate_tree_blocks calls get_tree_block_key for a block iff that block
has its ->key_ready equal false. Thus the BUG_ON in the latter function
cannot ever be triggered so remove it.
