By removing the early-exit when REMAP_FILE_DEDUP is set, we should be able to support the fideduperange ioctl, albeit less efficiently than if we handled some of the extent locking and comparison logic inside bcachefs. Extent comparison logic already exists inside of `__generic_remap_file_range_prep`. Signed-off-by: Reed Riley <reed@riley.engineer> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
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.
