Subject: [PATCH 06/12] staging: lustre: fid: add a connect flag for open by FID
Date: Wed, 27 Apr 2016 21:37:15 -0400 [thread overview]
Message-ID: <1461807441-3210-7-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1461807441-3210-1-git-send-email-jsimmons@infradead.org>
From: Lai Siyao <lai.siyao@intel.com>
Add OBD_CONNECT_OPEN_BY_FID for open by FID, if MDS supports this,
for open by FID, it won't retry with name if object with the FID
doesn't exist; while if client supports this, client won't pack
name in open request if FID is known.
