Subject: [PATCH 6/6] NFS: return -EAGAIN when skipped commit in nfs_commit_unstable_pages()
Date: Tue, 19 Apr 2011 11:00:09 +0800	[thread overview]
Message-ID: <20110419030532.902141228@intel.com> (raw)
In-Reply-To: 20110419030003.108796967@intel.com

[-- Attachment #1: nfs-fix-write_inode-retval.patch --]
[-- Type: text/plain, Size: 701 bytes --]

It's probably not sane to return success while redirtying the inode at
the same time in ->write_inode().
