+config EROFS_FS

+ depends on BLOCK
+ help
+ EROFS (Enhanced Read-Only File System) is a lightweight
+ read-only file system with modern designs (eg. page-sized
+ blocks, inline xattrs/data, etc.) for scenarios which need
+ high-performance read-only requirements, e.g. Android OS
+ for mobile phones and LIVECDs.
+
+ It also provides fixed-sized output compression support,
+ which improves storage density, keeps relatively higher
+ compression ratios, which is more useful to achieve high
+ performance for embedded devices with limited memory.

+ For daily use, say N.
