Author: jhb Date: Thu Feb 19 22:10:39 2009 New Revision: 188831 URL: http://svn.freebsd.org/changeset/base/188831 Log: Don't clear the attribute cache of a file when it is closed. A subsequent open() of the same file will load fresh attributes, so they do not need to be explicitly flushed in close() to guarantee close to open consistency. However, other file desciptors may still reference this file and clearing the attributes in close() forces those other file descriptors to fetch fresh attributes the next time they need them.
