2 | tristate "F2FS filesystem support (EXPERIMENTAL)" | |
3 | help | |
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. | |
8 | ||
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. | |
13 | ||
14 | If unsure, say N. | |

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. | |

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 | |

46 | Posix Access Control Lists (ACLs) support permissions for users and | |
47 | gourps beyond the owner/group/world scheme. | |
