.SH DESCRIPTION
.B dump.f2fs
is used to retrieve f2fs metadata (usually in a disk partition).
\fIdevice\fP is the special file corresponding to the device (e.g.

Currently, it can retrieve 1) a file given its inode number, 2) NAT
entries into a file, 3) SIT entries into a file, 4) SSA entries into
a file, 5) reverse information from the given block address.
