config F2FS_FS tristate "F2FS filesystem support (EXPERIMENTAL)" depends on BLOCK help F2FS is based on Log-structured File System (LFS), which supports versatile "flash-friendly" features. The design has been focused on addressing the fundamental issues in LFS, which are snowball effect of wandering tree and high cleaning overhead. Since flash-based storages show different characteristics according to the internal geometry or flash memory management schemes aka FTL, F2FS and tools support various parameters not only for configuring on-disk layout, but also for selecting allocation and cleaning algorithms. If unsure, say N. config F2FS_STAT_FS bool "F2FS Status Information" depends on F2FS_FS && DEBUG_FS default y help /sys/kernel/debug/f2fs/ contains information about all the partitions mounted as f2fs. Each file shows the whole f2fs information. /sys/kernel/debug/f2fs/status includes: - major file system information managed by f2fs currently - average SIT information about whole segments - current memory footprint consumed by f2fs. config F2FS_FS_XATTR bool "F2FS extended attributes" depends on F2FS_FS default y help Extended attributes are name:value pairs associated with inodes by the kernel or by users (see the attr(5) manual page, or visit <http://acl.bestbits.at/> for details). If unsure, say N. config F2FS_FS_POSIX_ACL bool "F2FS Access Control Lists" depends on F2FS_FS_XATTR select FS_POSIX_ACL default y help Posix Access Control Lists (ACLs) support permissions for users and gourps beyond the owner/group/world scheme. To learn more about Access Control Lists, visit the POSIX ACLs for Linux website <http://acl.bestbits.at/>. If you don't know what Access Control Lists are, say N
