+config EROFS_FS
+ tristate "EROFS filesystem support"
+ 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 have
+ high-performance read-only requirements, eg. firmwares in
+ mobile phone or LIVECDs.
+
+ It also provides VLE compression support, focusing on
+ random read improvements, keeping relatively lower
+ compression ratios, which is also useful for
+ high-performance devices with limited ROM space.
+
+ If unsure, say N.
+
+config EROFS_FS_DEBUG
+ bool "EROFS debugging feature"

+ Print erofs debugging messages and enable more BUG_ONs

+
+ For daily use, say N.

+config EROFS_FS_USE_VM_MAP_RAM
