2 tristate "F2FS filesystem support (EXPERIMENTAL)"
4 F2FS is based on Log-structured File System (LFS), which supports
5 versatile "flash-friendly" features. The design has been focused on
6 addressing the fundamental issues in LFS, which are snowball effect
7 of wandering tree and high cleaning overhead.
9 Since flash-based storages show different characteristics according to
10 the internal geometry or flash memory management schemes aka FTL, F2FS
11 and tools support various parameters not only for configuring on-disk
12 layout, but also for selecting allocation and cleaning algorithms.
17 bool "F2FS Status Information"
18 depends on F2FS_FS && DEBUG_FS
21 /sys/kernel/debug/f2fs/ contains information about all the partitions
22 mounted as f2fs. Each file shows the whole f2fs information.
24 /sys/kernel/debug/f2fs/status includes:
25 - major file system information managed by f2fs currently
26 - average SIT information about whole segments
27 - current memory footprint consumed by f2fs.
30 bool "F2FS extended attributes"
34 Extended attributes are name:value pairs associated with inodes by
35 the kernel or by users (see the attr(5) manual page, or visit
36 <http://acl.bestbits.at/> for details).
40 config F2FS_FS_POSIX_ACL
41 bool "F2FS Access Control Lists"
42 depends on F2FS_FS_XATTR
46 Posix Access Control Lists (ACLs) support permissions for users and
47 gourps beyond the owner/group/world scheme.
49 To learn more about Access Control Lists, visit the POSIX ACLs for
50 Linux website <http://acl.bestbits.at/>.
