We use below condition to check inline_xattr_size boundary:
if (!F2FS_OPTION(sbi).inline_xattr_size ||
F2FS_OPTION(sbi).inline_xattr_size >=
DEF_ADDRS_PER_INODE -
F2FS_TOTAL_EXTRA_ATTR_SIZE -
DEF_INLINE_RESERVED_SIZE -
DEF_MIN_INLINE_SIZE)
There is there problems in that check:
- we should allow inline_xattr_size equaling to min size of inline
{data,dentry} area.
- F2FS_TOTAL_EXTRA_ATTR_SIZE and inline_xattr_size are based on
different size unit, previous one is 4 bytes, latter one is 1 bytes.
- DEF_MIN_INLINE_SIZE only indicate min size of inline data area,
however, we need to consider min size of inline dentry area as well,
minimal inline dentry should at least contain two entries: '.' and
'..', so that min inline_dentry size is 40 bytes.
.bitmap 1 * 1 = 1
.reserved 1 * 1 = 1
.dentry 11 * 2 = 22
.filename 8 * 2 = 16
total 40

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.
