[PATCH] trivial: Fix stale definition of file-nr in documentation

[Xiaotian Feng]

commit 760df9 merged /proc/sys/fs documentation in Documentation/sysctl/
fs.txt and Documentation/filesystem/proc.txt, but stale file-nr definition
is remained. This patch add back the right fs-nr definition for 2.6 kernel.

-number of file handles. When the allocated file handles come

+Historically, the three values in file-nr denoted the number of
+allocated file handles, the number of allocated but unused file
+handles, and the maximum number of file handles. Linux 2.6 always
+reports 0 as the number of free file handles -- this is not an
+error, it just means that the number of allocated file handles
+exactly matches the number of used file handles.

+Attempts to allocate more file descriptors than file-max are
+reported with printk, look for "VFS: file-max limit <number>
+reached".
