Waiman Long e68d343d27 mm/kmemleak: move up cond_resched() call in page scanning loop Commit `bde5f6bc68` ("kmemleak: add scheduling point to kmemleak_scan()") added a cond_resched() call to the struct page scanning loop to prevent soft lockup from happening. However, soft lockup can still happen in that loop in some corner cases when the pages that satisfy the "!(pfn & 63)" check are skipped for some reasons. Fix this corner case by moving up the cond_resched() check so that it will be called every 64 pages unconditionally.

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.
