CONFIG_EROFS_FS: EROFS filesystem support

General informations

The Linux kernel configuration item CONFIG_EROFS_FS has multiple definitions:

EROFS filesystem support found in fs/erofs/Kconfig

The configuration item CONFIG_EROFS_FS:

Help text

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.

If unsure, say N.

Help text

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, 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 useful for high-performance devices with limited memory and ROM space.

If unsure, say N.
