Author: scottl Date: Thu May 30 17:17:22 2013 New Revision: 251145 URL: http://svnweb.freebsd.org/changeset/base/251145 Log: MFC r248504: Add a convenience macro bread_gb() to wrap a call to breadn_flags(). Comparing with bread(), it adds an argument to pass the flags to getblk(). The API implementation of bread() and friends is different in FreeBSD 9, so this merge is a little more complicated than the original commit.
