4	  This provides support for reading images from EROFS filesystem.
5	  EROFS (Enhanced Read-Only File System) is a lightweight read-only
6	  file system for scenarios which need high-performance read-only
7	  requirements.
8
9	  It also provides fixed-sized output compression support, which
10	  improves storage density, keeps relatively higher compression
11	  ratios, which is more useful to achieve high performance for
12	  embedded devices with limited memory.

20	  Enable fixed-sized output compression for EROFS.
21	  If you don't want to enable compression feature, say N.

25	depends on FS_EROFS_ZIP
26	select ZLIB
27	help
28	  Saying Y here includes support for reading EROFS file systems
29	  containing DEFLATE compressed data.  It gives better compression
30	  ratios than the default LZ4 format, while it costs more CPU
31	  overhead.
32
33	  DEFLATE support is an experimental feature for now and so most
34	  file systems will be readable without selecting this option.
35
36	  If unsure, say N.
