Mapping info from dump.f2fs:
i_addr[0x2d] cluster flag [0xfffffffe : 4294967294]
i_addr[0x2e] [0x 10428 : 66600]
i_addr[0x2f] [0x 10429 : 66601]
i_addr[0x30] [0x 1042a : 66602]
f2fs_io fiemap 37 1 /mnt/f2fs/disk-58390c8c.raw
Previsouly, it missed to align fofs and ofs_in_node to cluster_size,
result in adding incorrect read extent cache, fix it.
Before:
f2fs_update_read_extent_tree_range: dev = (253,48), ino = 5, pgofs = 37, len = 4, blkaddr = 66600, c_len = 3
After:
f2fs_update_read_extent_tree_range: dev = (253,48), ino = 5, pgofs = 36, len = 4, blkaddr = 66600, c_len = 3
Fixes: 94afd6d6e5 ("f2fs: extent cache: support unaligned extent")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
