commite51d68e76dupstream. When dquot_resume() was last updated, the argument that got passed to vfs_cleanup_quota_inode was incorrectly set. If type = -1 and dquot_load_quota_sb() returns a negative value, then vfs_cleanup_quota_inode() gets called with -1 passed as an argument, and this leads to an array-index-out-of-bounds bug. Fix this issue by correctly passing the arguments.

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.
