Subject: [PATCH 1/6] Add new FMODE flags: FMODE_32bithash and FMODE_64bithash
Date: Tue, 16 Aug 2011 13:25:42 +0200 [thread overview]
Message-ID: <20110816112542.1808464.78642.stgit@fsdevel3> (raw)
In-Reply-To: <20110816112536.1808464.7174.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().
