Split the checkpoint list of the transaction into two lists. In the first
list we keep the buffers that need to be submitted for IO. In the second
list are kept buffers that were already submitted and we just have to wait
for the IO to complete. This should simplify a handling of checkpoint
lists a bit and can eventually be also a performance gain.Signed-off-by: Jan Kara

Semaphore to mutex conversion.
The conversion was generated via scripts, and the result was validated
automatically via a script as well.Signed-off-by: Arjan van de Ven

This patch reverts commit f93ea411b73594f7d144855fd34278bcf34a9afc:
[PATCH] jbd: split checkpoint listsThis broke journal_flush() for OCFS2, which is its method of being sure
that metadata is sent to disk for another node.And two related commits 8d3c7fce2d20ecc3264c8d8c91ae3beacdeaed1b and
43c3e6f5abdf6acac9b90c86bf03f995bf7d3d92 with the subjects:
[PATCH] jbd: log_do_checkpoint fix
[PATCH] jbd: remove_transaction fixThese seem to be incremental bugfixes on the original patch and as such are
no longer needed.Signed-off-by: Mark Fasheh

While checkpointing we have to check that our transaction still is in the
checkpoint list *and* (not or) that it's not just a different transaction
with the same address.Signed-off-by: Jan Kara

We must be sure that the current data in buffer are sent to disk. Hence we
have to call ll_rw_block() with SWRITE.Signed-off-by: Jan Kara

Fix a bug in list scanning that can cause us to skip the last buffer on the
checkpoint list (and hence fail to do any progress under some rather
unfavorable conditions).The problem is we first do jh=next_jh and then test
} while (jh!=last_jh);
Hence we skip the last buffer on the list (if it was not the only buffer on
the list). As we already do jh=next_jh; in the beginning of the loop we
are safe to just remove the assignment in the end. It can happen that 'jh'
will be freed at the point we test jh != last_jh but that does not matter
as we never *dereference* the pointer.Signed-off-by: Jan Kara

Fix possible false assertion failure in log_do_checkpoint(). We might fail
to detect that we actually made a progress when cleaning up the checkpoint
lists if we don't retry after writing something to disk. The patch was
confirmed to fix observed assertion failures for several users.When we flushed some buffers we need to retry scanning the list.
Otherwise we can fail to detect our progress.Signed-off-by: Jan Kara

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
