In 'fs/xfs/libxfs/xfs_trans_resv.c', the comment for transaction of removing a
directory entry writes:
/* fs/xfs/libxfs/xfs_trans_resv.c begin */
/*
* For removing a directory entry we can modify:
* the parent directory inode: inode size
* the removed inode: inode size
...
xfs_calc_remove_reservation(
struct xfs_mount *mp)
{
return XFS_DQUOT_LOGRES(mp) +
xfs_calc_iunlink_add_reservation(mp) +
max((xfs_calc_inode_res(mp, 1) +
...
/* fs/xfs/libxfs/xfs_trans_resv.c end */
There has 2 inode size of space to be reserverd, but the actual code
for inode reservation space writes.
There only count for 1 inode size to be reserved in
'xfs_calc_inode_res(mp, 1)', rather than 2.

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.
