Hi Jens,

Hi,
I'm just back from firstly Edinburgh, and secondly holiday, and the
merge window is again upon us. I've added in the three pending patches
which were under test while I was away and then that should be it for
this time.
The main feature of interest this time is quota updates. There are

In function gfs2_rbm_from_block, it starts by checking if the block
falls within the first bitmap. It does so by checking if the rbm's
offset is less than (rbm->bi->bi_start + rbm->bi->bi_len) * GFS2_NBBY.
However, the first bitmap will always have bi_start==0. Therefore

This patch adds a structure to contain allocation parameters with
the intention of future expansion of this structure. The idea is
that we should be able to add more information about the allocation
in the future in order to allow the allocator to make a better job
of placing the requests on-disk.
There is no need for a paramater which relates to the internals
of quota to be exposed to users. The only possible use would be
to turn it up so large that the memory allocation fails. So lets
remove it and set it to a sensible value which ensures that we
don't ask for multipage allocations.

The reservation for an inode should be cleared when it is truncated so
that we can start again at a different offset for future allocations.
We could try and do better than that, by resetting the search based on
where the truncation started from, but this is only a first step.
In addition, there a
Currently glocks have an atomic reference count and also a spinlock

This is a respin of the original patch. As Steve pointed out, the
introduction of field bii makes it easy to eliminate bi itself.
This revised patch does just that, replacing bi with bii.
This patch adds a new field to the rbm structure, called bii,
which is an index into the
There should be no functional change bar the removal of a
test of the MS_READONLY flag which would never be reachable.
This merges the common code from qd_fish and qd_trylock into
a single function and calls it from both those places.

Now that gfs2_quota_sync can be potentially called from multiple

The function qd_trylock was not a trylock despite its name and

Since the previous patch eliminated bi in favor of bii, this follow-on
patch needed to be adjusted accordingly. Here is the revised version.

When we used try locks for rgrps on block allocations, it was important
to clear the flags field so that we used a blocking hold on the glock.
Now that we're not doing try locks, clearing flags is unnecessary, and
a waste of time. In fact, it's probably doing the wrong thing be

This patch introduces a new field in the bitmap structure called
bi_blocks. Its purpose is to save us from constantly multiplying
bi_len by the constant GFS2_NBBY. It also paves the way for more
optimization in a future patch.

When setting the starting point for block allocation, there were calls
to both gfs2_rbm_to_block() and gfs2_rbm_from_block() in the common case
of there being an active reservation. The gfs2_rbm_from_block() function
can be quite slow, and since the two conversions were effectively a
no-op, it make
This patch adds reflink support to the quota data cache. It
looks a bit strange because we still don't have a sensible

later patches though.
The intent here is just to swap the current ref count for

By using the generic list_lru code, we can now separate the
per sb quota list locking from the lru locking. The lru
lock is made into the inner-most lock.
As a result of this new lock order, we may occasionally see
items on the per-sb quota list which are "dead" so that the
