With below mkfs and mount option, generic/339 of fstest will report that
scratch image becomes corrupted.
MKFS_OPTIONS -- -O extra_attr -O project_quota -O inode_checksum -O flexible_inline_xattr -O inode_crtime -f /dev/zram1
MOUNT_OPTIONS -- -o acl,user_xattr -o discard,noinline_xattr /dev/zram1 /mnt/scratch_f2fs
[ASSERT] (f2fs_check_dirent_position:1315) --> Wrong position of dirent pino:1970, name: (...)
level:8, dir_level:0, pgofs:951, correct range:[900, 901]
In old kernel, inline data and directory always reserved 200 bytes in
inode layout, even if inline_xattr is disabled, then new kernel tries
to retrieve that space for non-inline xattr inode, but for inline dentry,
its layout size should be fixed, so we just keep that reserved space.
But the problem here is that, after inline dentry conversion, inline
dentry layout no longer exists, if we still reserve inline xattr space,
after dents updates, there will be a hole in inline xattr space, which
can break hierarchy hash directory structure.
This patch fixes this issue by retrieving inline xattr space after
inline dentry conversion.

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.
