Subject: [PATCH 1/4] Add new FMODE flags: FMODE_32bithash and FMODE_64bithash
Date: Mon, 08 Aug 2011 17:37:58 +0200	[thread overview]
Message-ID: <20110808153758.1872437.35029.stgit@fsdevel3> (raw)
In-Reply-To: <20110808153432.1872437.85783.stgit@fsdevel3>

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