396 # a gzip-compressed kernel as example, to illustrate it:
398 # The file layout of gzip compressed kernel is:
406 #    compressed data blocks[N]
434 # compressed data is placed at the end of the buffer.  The output pointer
436 # where the compressed data starts. Problems will occur when the output
441 # triggered by data whose compressed form is larger than the uncompressed
444 # The worst case at the block level is a growth of the compressed data
447 # The worst case internal to a compressed block is very hard to figure.
457 # block will stop the byte before the compressed data for a block begins.
458 # To avoid problems with the compressed data's meta information an extra 18
466 # Above analysis is for decompressing gzip compressed kernel only. Up to
475 # LZ4 is even worse: data that cannot be further compressed grows by 0.4%,
481 # ZSTD compressed data grows by at most 3 bytes per 128K, and only has a 22
