from cleaning overhead during high utilization. Conversely, the threaded log scheme suffers from random writes, but no cleaning process is needed. F2FS adopts a hybrid scheme where the copy-and-compaction scheme is adopted by default, but the policy is dynamically changed to the threaded log scheme according to the file system status.
820:
F2FS supports two victim selection policies: greedy, and cost-benefit algorithms. In the greedy algorithm, F2FS selects a victim segment having the smallest number of valid blocks. In the cost-benefit algorithm, F2FS selects a victim segment according to the segment age and the number of valid blocks
719:
When F2FS finds a file name in a directory, first a hash value of the file name is calculated. Then, F2FS scans the hash table in level #0 to find the dentry consisting of the file name and its inode number. If not found, F2FS scans the next hash table in level #1. In this way, F2FS scans hash tables
630:
The key data structure is the "node". Similar to traditional file structures, F2FS has three types of nodes: inode, direct node, indirect node. F2FS assigns 4 KB to an inode block which contains 923 data block indices, two direct node pointers, two indirect node pointers, and one double indirect

has two schemes for free space management: threaded log and copy-and-compaction. The copy-and-compaction scheme which is known as cleaning, is well-suited for devices showing very good sequential write performance, since free segments are served all the time for writing new data. However, it suffers
807:
In order to align F2FS with underlying flash-based storage, F2FS allocates a segment in a unit of a section. F2FS expects the section size to be the same as the garbage collection unit size in FTL. With respect to the mapping granularity in FTL, F2FS allocates each section of the active logs to as
415:
Note, that by default F2FS uses "posix" fsync scheme, which carries higher risks of leaving the file system in dirty state during unclean shutdown (as it does not guarantee atomicity of write operations) at the benefit of better performance. There is a more stringent method that respects hardware
621:
F2FS uses the checkpoint scheme to maintain file system integrity. At mount time, F2FS first tries to find the last valid checkpoint data by scanning the CP area. In order to reduce the scanning time, F2FS uses only two copies of the CP. One of them always indicates the last valid data, which is
563:
F2FS divides the whole volume into a number of segments, each of which is fixed at 2 MB. A section is composed of consecutive segments, and a zone consists of a set of sections. By default, section and zone sizes are set to the same size, but users can easily modify the size with
816:
F2FS does cleaning both on demand, and in the background. On-demand cleaning is triggered when there are not enough free segments to serve VFS calls. The background cleaner is executed by a kernel thread, and triggers the cleaning job when the system is idle.
612:
In order to avoid misalignment between file system and flash storage, F2FS aligns the start block address of the CP with the segment size. It also aligns the Main Area start block address with the zone size by reserving some segments in the SSA area.
637:
Note that all the node blocks are mapped by the NAT, which means that the location of each node is translated by the NAT. To mitigate the wandering tree problem, F2FS is able to cut off the propagation of node updates caused by leaf data writes.
715:
level #0 A(2B) level #1 A(2B) - A(2B) level #2 A(2B) - A(2B) - A(2B) - A(2B) ... level #N/2 A(2B) - A(2B) - A(2B) - A(2B) - A(2B) - ... - A(2B) ... level #N A(4B) - A(4B) - A(4B) - A(4B) - A(4B) - ... - A(4B)
824:
In order to identify whether the data in the victim segment are valid or not, F2FS manages a bitmap. Each bit represents the validity of a block, and the bitmap is composed of a bit stream covering whole blocks in the Main Area.
697:
F2FS implements multi-level hash tables for the directory structure. Each level has a hash table with a dedicated number of hash buckets as shown below. Note that "A(2B)" means a bucket includes 2 data blocks.

in order to address the log block thrashing problem present in the greedy algorithm. F2FS uses the greedy algorithm for on-demand cleaning, the background cleaner uses the cost-benefit algorithm.
