A memory block is allocated through kmalloc(), and its return value is assigned to the pointer oinfo. However, oinfo->dqi_gqinode is not initialized but it is accessed in: iput(oinfo->dqi_gqinode); To fix this possible uninitialized-variable access, assign NULL to oinfo->dqi_gqinode, and add ocfs2_qinfo_lock_res_init() behind the assignment in ocfs2_local_read_info(). Remove ocfs2_qinfo_lock_res_init() in ocfs2_global_read_info().

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.
