This exists internal to ctree.c, however btrfs check needs to use it for some of its operations. I'd rather not duplicate that code inside of btrfs check as this is low level and I want to keep this code in one place, so rename the function to btrfs_del_ptr and export it so that it can be used inside of btrfs-progs safely. Add a comment to make sure this doesn't get removed by a future cleanup. Signed-off-by: Josef Bacik <josef@toxicpanda.com> Signed-off-by: David Sterba <dsterba@suse.com>
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.
