Subject: [PATCH 4 1/4] Add new FMODE flags: FMODE_32bithash and FMODE_64bithash
Date: Mon, 09 Jan 2012 11:16:33 +0100	[thread overview]
Message-ID: <20120109101633.2218398.60217.stgit@localhost.localdomain> (raw)
In-Reply-To: <20120109101628.2218398.94904.stgit@localhost.localdomain>

Those flags are supposed to be set by NFS readdir() to tell ext3/ext4
to 32bit (NFSv2) or 64bit hash values (offsets) in seekdir().
