We are currently treating any non-zero return value from btrfs_next_leaf() the same way, by going to the code that inserts a new checksum item in the tree. However if btrfs_next_leaf() returns an error (a value < 0), we should just stop and return the error, and not behave as if nothing has happened, since in that case we do not have a way to know if there is a next leaf or we are currently at the last leaf already. So fix that by returning the error from btrfs_next_leaf(). Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: David Sterba <dsterba@suse.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.
