Subject: Re: [PATCH 09/10] xfs: nowait aio support
Date: Sun, 28 May 2017 02:31:13 -0700
Message-ID: <20170528093113.GB14519@infradead.org> (raw)
In-Reply-To: <20170524164150.9492-10-rgoldwyn-l3A5Bk7waGM@public.gmane.org>

Despite my previous reviewed-by tag this will need another fix:

xfs_file_iomap_begin needs to return EAGAIN if we don't have the extent
list in memoery already.  E.g. something like this:

	if ((flags & IOMAP_NOWAIT) && !(ip->i_d.if_flags & XFS_IFEXTENTS)) {
		error = -EAGAIN;
		goto out_unlock;
	}

right after locking the ilock.
