Subject: [31/34] nilfs2: fix sync silent failure
Date: Mon, 24 May 2010 16:00:03 -0700 [thread overview]
Message-ID: <20100524230352.098168879@clark.site> (raw)
In-Reply-To: <20100524230418.GA12770@kroah.com>
2.6.34-stable review patch. If anyone has any objections, please let us know.
------------------
From: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
commit 973bec34bfc1bc2465646181653d67f767d418c8 upstream.
As of 32a88aa1, __sync_filesystem() will return 0 if s_bdi is not set.
And nilfs does not set s_bdi anywhere. I noticed this problem by the
warning introduced by the recent commit 5129a469 ("Catch filesystem
lacking s_bdi").
WARNING: at fs/super.c:959 vfs_kern_mount+0xc5/0x14e()
Hardware name: PowerEdge 2850
Modules linked in: nilfs2 loop tpm_tis tpm tpm_bios video shpchp pci_hotplug output dcdbas
Pid: 3773, comm: mount.nilfs2 Not tainted 2.6.34-rc6-debug #38

This ensures to set s_bdi for nilfs and fixes the sync silent failure.
