The gfs2_fsync() function was doing a journal flush on each
and every call. While this is correct, its also a lot of
overhead. This patch means that on fdatasync flushes we
rely on the VFS to flush the data for us and we don't do
a journal flush unless we really need to.
We have to do a journal flush for stuffed files though because
they have the data and the inode metadata in the same block.
Journaled files also need a journal flush too of course.

[GFS2] Mount problem with the GFS2 code
While mounting the gfs2 filesystem,our test team had a problem and we
got this error message.
=======================================================
GFS2: fsid=: Trying to join cluster "lock_nolock", "dasde1"
GFS2: fsid=dasde1.0: Joined cluster. Now mounting FS...
GFS2: not a GFS2 filesystem
GFS2: fsid=dasde1.0: can't read superblock: -22
==========================================================================
On debugging further we found that problem is while reading the super
block(gfs2_read_super) and comparing the magic number in it.
When I replace the submit_bio() call(present in gfs2_read_super) with
the sb_getblk() and ll_rw_block(), mount operation succeded.
On further analysis we found that before calling submit_bio(),
bio->bi_sector was set to "sector" variable. This "sector" variable has
the same value of bh->b_blocknr(block number). Hence there is a need to
multiply this valuwith (blocksize >> 9)(9 because,sector size
2^9,samething happens in ll_rw_block also, before calling submit_bio()).
So I have developed the patch which solves this problem. Please let me
know your comments.

[DLM] don't accept replies to old recovery messages
We often abort a recovery after sending a status request to a remote node.
We want to ignore any potential status reply we get from the remote node.
If we get one of these unwanted replies, we've often moved on to the next
recovery message and incremented the message sequence counter, so the
reply will be ignored due to the seq number. In some cases, we've not
moved on to the next message so the seq number of the reply we want to
ignore is still correct, causing the reply to be accepted. The next
recovery message will then mistake this old reply as a new one.
To fix this, we add the flag RCOM_WAIT to indicate when we can accept a
new reply. We clear this flag if we abort recovery while waiting for a
reply. Before the flag is set again (to allow new replies) we know that
any old replies will be rejected due to their sequence number. We also
initialize the recovery-message sequence number to a random value when a
lockspace is first created. This makes it clear when messages are being
rejected from an old instance of a lockspace that has since been
recreated.

This fixes a bug which resulted in poor performance due to flushing
the journal too often. The code path in question was via the inode_go_sync()
function in glops.c. The solution is not to flush the journal immediately
when inodes are ejected from memory, but batch up the work for glockd to
deal with later on. This means that glocks may now live on beyond the end of
the lifetime of their inodes (but not very much longer in the normal case).
Also fixed in this patch is a bug (which was hidden by the bug mentioned above) in
calculation of the number of free journal blocks.
The gfs2_logd process has been altered to be more responsive to the journal
filling up. We now wake it up when the number of uncommitted journal blocks
has reached the threshold level rather than trying to flush directly at the
end of each transaction. This again means doing fewer, but larger, log
flushes in general.
