Currently, the code that performs CoW remapping after a write has this odd behavior where it walks /backwards/ through the data fork to remap extents in reverse order. Earlier, we rewrote the reflink remap function to use deferred bmap log items instead of trying to cram as much into the first transaction that we could. Now do the same for the CoW remap code. There doesn't seem to be any performance impact; we're just making better use of code that we added for the benefit of reflink. Signed-off-by: Darrick J.

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.
