NeilBrown ff8eb22e5b staging: lustre: fix bug in osc_enter_cache_try 
[ Upstream commit 2fab9faf9b ]

The lustre-release patch commit bdc5bb52c554 ("LU-4933 osc:
Automatically increase the max_dirty_mb") changed

-       if (cli->cl_dirty + PAGE_CACHE_SIZE <= cli->cl_dirty_max &&
+       if (cli->cl_dirty_pages < cli->cl_dirty_max_pages &&

When this patch landed in Linux a couple of years later, it landed as

-       if (cli->cl_dirty + PAGE_SIZE <= cli->cl_dirty_max &&
+       if (cli->cl_dirty_pages <= cli->cl_dirty_max_pages &&

which is clearly different ('<=' vs '<'), and allows cl_dirty_pages to
increase beyond cl_dirty_max_pages - which causes a latter assertion
to fails.

README 

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
