F2FS

Log based file-system

ATGC

Age-Threshold based Garbage Collection uses age to optimized garbage collection calls[1]

History

6.11

FS_IOC_GETFSSYSFSPATH was added to F2FS, it was added to EXT4/bcachefs on 6.10 and created on 6.9. it exist to give a standard way to access the SYSFS path that in time should be added to all FS. made by Kent Overstreet.

enables #ATGC dynamically in some cases.[2]

6.12

More conversion to folios (in I/O Cod path) [3]

6.13

The F2FS filesystem has a new feature, called "device aliasing", that allows a portion of a block device to be set aside. "Essentially, this mechanism allows a portion of the f2fs area to be temporarily reserved and used by another filesystem or for different purposes. Once that external usage is complete, the device aliasing file can be deleted, releasing the reserved space back to F2FS for its own use."[4]
