jbd2: Drop jbd2_space_needed()
The function is now just a trivial wrapper returning journal->j_max_transaction_buffers. Drop it. Reviewed-by: Theodore Ts'o <tytso@mit.edu> Signed-off-by: Jan Kara <jack@suse.cz> Link: https://lore.kernel.org/r/20191105164437.32602-19-jack@suse.cz Signed-off-by: Theodore Ts'o <tytso@mit.edu>
