commit 3470ca24e60578b3306a909588c7a269eeef51d6
Author: Christoph Hellwig <hch@xxxxxxxxxxxxx>
Date: Thu Sep 30 02:25:56 2010 +0000
xfs: do not use xfs_mod_incore_sb_batch for per-cpu counters
Update the per-cpu counters manually in xfs_trans_unreserve_and_mod_sb
and remove support for per-cpu counters from xfs_mod_incore_sb_batch
to simplify it. And added benefit is that we don't have to take
m_sb_lock for transactions that only modify per-cpu counters.

commit c7e2068007b60c073bd7e5415e4db114ff596920
Author: Christoph Hellwig <hch@xxxxxxxxxxxxx>
Date: Thu Sep 30 02:25:55 2010 +0000
xfs: do not use xfs_mod_incore_sb for per-cpu counters
Export xfs_icsb_modify_counters and always use it for modifying
the per-cpu counters. Remove support for per-cpu counters from
xfs_mod_incore_sb to simplify it.

commit 893eb9d7d7755ab63f57d5426dc2639fb8a06ccd
Author: Christoph Hellwig <hch@xxxxxxxxxxxxx>
Date: Thu Sep 30 02:25:54 2010 +0000
xfs: remove XFS_MOUNT_NO_PERCPU_SB
Fail the mount if we can't allocate memory for the per-CPU counters.
This is consistent with how we handle everything else in the mount
path and makes the superblock counter modification a lot simpler.
