Inside function __cow_file_range_inline() since the inlined data no longer take any data space, we need to free up the reserved space. However the code is still using the old page size == sector size assumption, and will not handle subpage case well. Thankfully it is not going to cause any problems because we have two extra safe nets: - Inline data extents creation is disabled for sector size < page size cases for now But it won't stay that for long. - btrfs_qgroup_free_data() will only clear ranges which have been already reserved So even if we pass a range larger than what we need, it should still be fine, especially there is only reserved space for a single block at file offset 0 of an inline data extent. But just for the sake of consistency, fix the call site to use sectorsize instead of page size.

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 reStructuredText 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.
