When we mount the file system we do something like this:
while (1) {
lookup fs roots;
for (i = 0; i < num_roots; i++) {
ret = btrfs_orphan_cleanup(roots[i]);
if (ret)
break;
btrfs_put_root(roots[i]);
}
}
for (; i < num_roots; i++)
btrfs_put_root(roots[i]);
As you can see if we break in that inner loop we just go back to the
outer loop and lose the fact that we have to drop references on the
remaining roots we looked up. Fix this by making an out label and
jumping to that on error so we don't leak a reference to the roots we
looked up.

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.
