"max_bpt_f="1k|...|128g sets the limit for the memory size of the

block pointer list of a single file. max_bpt_f is never larger

than max_bpt. If either is set to violate this rule, the other

"bpt_free_ratio="-1|[0.0...1.0] sets a threshold for switching to

block pointer discarding during compression. If less than the

given fraction of the max_bpt_f= memory is free, then block
|

pointers of compression filters get discarded after size

assessment. This causes a third read run of the input file during

the production of the ISO filesystem. Value -1 disables this

feature.
