Author: rmacklem Date: Mon May 5 01:07:56 2014 New Revision: 265340 URL: http://svnweb.freebsd.org/changeset/base/265340 Log: MFC: r264681 Modify the NFSv4 client open/create RPC so that it acquires post-open/create directory attributes. This allows the RPC to name cache the newly created file and reduces the lookup RPC count by about 10% for software builds.
