..............................................................................
File Content
gc_urgent_sleep_time This parameter controls sleep time for gc_urgent.
500 ms is set by default. See above gc_urgent.
gc_min_sleep_time This tuning parameter controls the minimum sleep
time for the garbage collection thread. Time is
in milliseconds.
gc_max_sleep_time This tuning parameter controls the maximum sleep
time for the garbage collection thread. Time is
in milliseconds.
gc_no_gc_sleep_time This tuning parameter controls the default sleep
time for the garbage collection thread. Time is
in milliseconds.
gc_idle This parameter controls the selection of victim
policy for garbage collection. Setting gc_idle = 0
(default) will disable this option. Setting
gc_idle = 1 will select the Cost Benefit approach
& setting gc_idle = 2 will select the greedy approach.
gc_urgent This parameter controls triggering background GCs
urgently or not. Setting gc_urgent = 0 [default]
makes back to default behavior, while if it is set
to 1, background thread starts to do GC by given
gc_urgent_sleep_time interval.
reclaim_segments This parameter controls the number of prefree
segments to be reclaimed. If the number of prefree
segments is larger than the number of segments
in the proportion to the percentage over total
volume size, f2fs tries to conduct checkpoint to
reclaim the prefree segments to free segments.
By default, 5% over total # of segments.
main_blkaddr This value gives the first block address of
MAIN area in the partition.
max_small_discards This parameter controls the number of discard
commands that consist small blocks less than 2MB.
The candidates to be discarded are cached until
checkpoint is triggered, and issued during the
checkpoint. By default, it is disabled with 0.
discard_granularity This parameter controls the granularity of discard
command size. It will issue discard commands iif
the size is larger than given granularity. Its
unit size is 4KB, and 4 (=16KB) is set by default.
The maximum value is 128 (=512KB).
reserved_blocks This parameter indicates the number of blocks that
f2fs reserves internally for root.
batched_trim_sections This parameter controls the number of sections
to be trimmed out in batch mode when FITRIM
conducts. 32 sections is set by default.
ipu_policy This parameter controls the policy of in-place
updates in f2fs. There are five policies:
0x01: F2FS_IPU_FORCE, 0x02: F2FS_IPU_SSR,
0x04: F2FS_IPU_UTIL, 0x08: F2FS_IPU_SSR_UTIL,
0x10: F2FS_IPU_FSYNC.
min_ipu_util This parameter controls the threshold to trigger
in-place-updates. The number indicates percentage
of the filesystem utilization, and used by
F2FS_IPU_UTIL and F2FS_IPU_SSR_UTIL policies.
min_fsync_blocks This parameter controls the threshold to trigger
in-place-updates when F2FS_IPU_FSYNC mode is set.
The number indicates the number of dirty pages
when fsync needs to flush on its call path. If
the number is less than this value, it triggers
in-place-updates.
min_seq_blocks This parameter controls the threshold to serialize
write IOs issued by multiple threads in parallel.
min_hot_blocks This parameter controls the threshold to allocate
a hot data log for pending data blocks to write.
min_ssr_sections This parameter adds the threshold when deciding
SSR block allocation. If this is large, SSR mode
will be enabled early.
ram_thresh This parameter controls the memory footprint used
by free nids and cached nat entries. By default,
1 is set, which indicates 10 MB / 1 GB RAM.
ra_nid_pages When building free nids, F2FS reads NAT blocks
ahead for speed up. Default is 0.
dirty_nats_ratio Given dirty ratio of cached nat entries, F2FS
determines flushing them in background.
max_victim_search This parameter controls the number of trials to
find a victim segment when conducting SSR and
cleaning operations. The default value is 4096
which covers 8GB block address range.
migration_granularity For large-sized sections, F2FS can stop GC given
this granularity instead of reclaiming entire
section.
dir_level This parameter controls the directory level to
support large directory. If a directory has a
number of files, it can reduce the file lookup
latency by increasing this dir_level value.
Otherwise, it needs to decrease this value to
reduce the space overhead. The default value is 0.
cp_interval F2FS tries to do checkpoint periodically, 60 secs
by default.

Compression implementation
--------------------------
- New term named cluster is defined as basic unit of compression, file can
be divided into multiple clusters logically. One cluster includes 4 << n
(n >= 0) logical pages, compression size is also cluster size, each of
cluster can be compressed or not.
- In cluster metadata layout, one special block address is used to indicate
cluster is compressed one or normal one, for compressed cluster, following
metadata maps cluster to [1, 4 << n - 1] physical blocks, in where f2fs
stores data including compress header and compressed data.
- In order to eliminate write amplification during overwrite, F2FS only
support compression on write-once file, data can be compressed only when
all logical blocks in file are valid and cluster compress ratio is lower
than specified threshold.
- To enable compression on regular inode, there are three ways:
* chattr +c file
* chattr +c dir; touch dir/file
* mount w/ -o compress_extension=ext; touch file.ext

Dirhash keys
------------
For directories that are indexed using a secret-keyed dirhash over the
plaintext filenames, the KDF is also used to derive a 128-bit
SipHash-2-4 key per directory in order to hash filenames. This works
just like deriving a per-file encryption key, except that a different
KDF context is used. Currently, only casefolded ("case-insensitive")
encrypted directories use this style of hashing.

Adiantum is a (primarily) stream cipher-based mode that is fast even
on CPUs without dedicated crypto instructions. It's also a true
wide-block mode, unlike XTS. It can also eliminate the need to derive
per-file keys. However, it depends on the security of two primitives,
XChaCha12 and AES-256, rather than just one. See the paper

watermark_boost_factor:
This factor controls the level of reclaim when memory is being fragmented.
It defines the percentage of the high watermark of a zone that will be
reclaimed if pages of different mobility are being mixed within pageblocks.
The intent is that compaction has less work to do in the future and to
increase the success rate of future high-order allocations such as SLUB
allocations, THP and hugetlbfs pages.
To make it sensible with respect to the watermark_scale_factor parameter,
the unit is in fractions of 10,000. The default value of 15,000 means
that up to 150% of the high watermark will be reclaimed in the event of
a pageblock being mixed due to fragmentation. The level of reclaim is
determined by the number of fragmentation events that occurred in the
recent past. If this value is smaller than a pageblock then a pageblocks
worth of pages will be reclaimed (e.g. 2MB on 64-bit x86). A boost factor
of 0 will disable the feature.
