26 gc_idle = 1 will select the Cost Benefit approach & setting
28 gc_idle = 3 will select the age-threshold based approach.
49 Description: Controls the in-place-update policy.
75 Description: Controls the FS utilization condition for the in-place-update
81 Description: Controls the dirty page count condition for the in-place-update
120 faster, at the cost of higher latency for incoming I/O.
257 Supported on-disk features:
314 little bit aggressively. always uses cost benefit GC approach,
315 and will override age-threshold GC approach if ATGC is enabled
319 always uses cost benefit GC approach, and will override
320 age-threshold GC approach if ATGC is enabled at the same time.
343 - Query: cat /sys/fs/f2fs/<disk>/extension_list
344 - Add: echo '[h/c]extension' > /sys/fs/f2fs/<disk>/extension_list
345 - Del: echo '[h/c]!extension' > /sys/fs/f2fs/<disk>/extension_list
346 - [h] means add/del hot file extension
347 - [c] means add/del cold file extension

674 This is a read-only entry.
832 Description: It controls max read extent count for per-inode, the value of threshold
838 Description: It reclaims the given KBs of file-backed pages registered by

897 - "perf": Hash-only lookup.
898 - "compat": Hash-based lookup with a linear search fallback enabled
899 - "auto:perf": lookup_mode is auto and fallback is disabled on-disk

918 Description: Indicates the hint section between the first device and others in multi-devices
921 scenarios where multi-devices are mapped to the same dm device.
926 Description: Controls write priority in multi-devices setups. A value of 0 means normal writing.
