[Ocfs2-devel] flush

[Wim Coekaerts <wim.coekaerts@oracle.com>]

for those that are going to be awake now ;-)

sys_close() -> filp_close() -> ocfs_fops() -> ocfs_flush() -> fsync_buffers_list()

that happens on close. flush causes a sync to disk
so

untar of a full tree took 6:15 min
then took out the ocfs_sync_inode() from ocfs_file_release()
then lowered heartbeat to 1 per second nad commit interval now at 5
seconds

then went down to bout 4:30 minutes

then noticed the flush during untar, so I got rid of ocfs_flush() as a
test
went down to bout 2 minutes, however things are inconsistent
so it's not tha simple .but that's a huge part of the remaining
bottlenecks when comparing stuff to ext3
