Subject: [PATCH] NFS: return -EAGAIN when skipped commit in nfs_commit_unstable_pages()
Date: Fri, 10 Jun 2011 22:04:59 +0800 [thread overview]
Message-ID: <20110610140459.GA8021@localhost> (raw)
It's confusing to return success while redirtying the inode at the
same time in ->write_inode(). Return -EAGAIN to indicate that we've
not finished with this inode.
Impact: it's a cleanup, not bug fix.
