Author: rmacklem Date: Sun Sep 9 21:00:45 2012 New Revision: 240289 URL: http://svn.freebsd.org/changeset/base/240289
Log: Add a simple printf() based debug facility to the new nfs client. Use it for a printf() that can be harmlessly generated for mmap()'d files. It will be used extensively for the NFSv4.1 client. Debugging printf()s are enabled by setting vfs.nfs.debuglevel to a non-zero value. The higher the value, the more debugging printf()s.
