There is no good reason to have two different routines for freeing perag structures for the unmount and error cases. Add two arguments to specify the range of AGs to free to xfs_free_perag, and use that to replace xfs_free_unused_perag_range. The addition RCU grace period for the error case is harmless, and the extra check for the AG to actually exist is not required now that the callers pass the exact known allocated range.

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.
