Hi Dave,

Here I am reposting your xfssyncd series.  I want to make sure that
we're all on the same page.  In particular, are we all happy with patch
6, 'xfs: xfs_sync_data is redundant'?

Version 4:
- updated 'xfs: xfs_sync_data is redundant' with cleanups to the 
  xfs_flush_inodes interface as per Christoph's request,
- updated 'xfs: xfs_sync_data is redundant', folding in changes from 
- fixed a minor typo in xfs: 'syncd workqueue is no more', renaming the 
  log worker from 'xfs-reclaim' to 'xfs-log'.

I was going to rush this in for the 3.7 merge window.  However in the
light of the issues with patch 6 and Linus's comment here:
http://lkml.org/lkml/2012/9/30/152 and Stephen's comment here:
https://lkml.org/lkml/2012/9/23/144, I think it wiser to behave.  3.7
is stable without this series, so I will merge it for 3.8.

Once we have an agreement that patch 6 is ready I will pull this in to the
master branch first thing after the 3.7-rc1 merge from upstream.


Version 3 of the patchset I described here:


This patchset reliably exposed the log->l_last_sync_lsn problem I
just posted a fix for.

Version 3:
- per-mount log and reclaim workqueues instead of a generic mount
- reordering of some of the patches as Christoph requested.
- fixed the writeback_inodes_sb_if_idle deadlock by moving it all
  the way back up the write stack to xfs_file_aio_buffered_write
  where we were just flushing the current file to avoid deadlocking
  on it anyway.
- reintroduced xfs_flush_inodes() as a wrapper for
- rebased on a current TOT.

Version 2:
- fix writeback_inodes_sb_if_idle call in xfs_create()
- refreshed patch 13 before sending.
