commit9594497f2cupstream. The nfsd4_blocked_lock->nbl_time timestamp is recorded in jiffies, but then compared to a CLOCK_REALTIME timestamp later on, which makes no sense. For consistency with the other timestamps, change this to use a time_t. This is a change in behavior, which may cause regressions, but the current code is not sensible. On a system with CONFIG_HZ=1000, the 'time_after((unsigned long)nbl->nbl_time, (unsigned long)cutoff))' check is false for roughly the first 18 days of uptime and then true for the next 49 days.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
