[Ocfs2-devel] [PATCH 0/40] ocfs2: Detach ocfs2 metadata I/O from struct inode
The following series of patches attempts to detach metadata I/O from
struct inode. They are currently tied together pretty tightly.
Metadata reads happen via the ocfs2_read_blocks() functions, writes via
both jbd2 and ocfs2_write_blocks().
- Each inode has a cache of associated metadata blocks stored on its
ip_metadata_cache member. The ocfs2_read/write_blocks() functions
take a struct inode to access this member.
- The journal mostly doesn't care about inodes. It does, however, need
to set the transaction id on the inode so that dlmglue knows when an
inode needs to checkpoint.
- All the metadata I/O paths use ip_io_mutex to synchronize their
actions against each other.
The problem is that if someone wants to use our metadata I/O facilities,
they have to have a struct inode. But not everything in ocfs2 is an
inode (even if it seems that way sometimes). So we want to disconnect
them.
It turns out that most of what goes on is about ocfs2_caching_info. So
if we move the last few relevant bits to ocfs2_caching_info, we can then
embed ocfs2_caching_info into another structure just as easily as we do
inside struct inode. That's the theory, anyway.
The first three patches move the cache code to ocfs2_caching_info
entirely. The functions affecting the metadata cache, like
ocfs2_set_buffer_uptodate(), etc, take a struct ocfs2_caching_info
instead of a struct inode. That sort of thing. It's nice and easy.
The next three patches move the journal transaction ids to struct
ocfs2_caching_info. When they are done, the ocfs2_journal_access*()
functions take a stuct ocfs2_caching_info, and the dlmglue checks the
ocfs2_caching_info regarding checkpoints. So it only takes us six
patches to isolate ocfs2_caching_info in the metadata I/O API.
The remaining 34 patches slowly but surely move alloc.c to the new API.
Our btree code is heavily invested in the idea that all btrees are
rooted, somehow, at an inode. Since we want to root a btree at a
non-inode, we need to fix that. The good news, of course, is that the
ocfs2_extent_tree abstraction is already there to rescue us. We attach
the ocfs2_caching_info to a particular ocfs2_extent_tree, and we can
then send that ocfs2_extent_tree down through the btree code. At the
end of this series, the generic btree code doesn't reference struct
inode at all.
There are a lot of patches because this entire series is supposed to be
isomorphic. No behavior is to change, just the flexibility of our API.
Thus, each patch tries to be readily understandable. Thank you for your
patience!

[Ocfs2-devel] [PATCH 01/40] ocfs2: Make the ocfs2_caching_info structure self-contained.
We want to use the ocfs2_caching_info structure in places that are not
inodes. To do that, it can no longer rely on referencing the inode
directly.
This patch moves the flags to ocfs2_caching_info->ci_flags, stores
pointers to the parent's locks on the ocfs2_caching_info, and renames
the constants and flags to reflect its independant state.

[Ocfs2-devel] [PATCH 02/40] ocfs2: Change metadata caching locks to an operations structure.
We don't really want to cart around too many new fields on the
ocfs2_caching_info structure. So let's wrap all our access of the
parent object in a set of operations. One pointer on caching_info, and
more flexibility to boot.

[Ocfs2-devel] [PATCH 03/40] ocfs2: Take the inode out of the metadata read/write paths.
We are really passing the inode into the ocfs2_read/write_blocks()
functions to get at the metadata cache. This commit passes the cache
directly into the metadata block functions, divorcing them from the
inode.

[Ocfs2-devel] [PATCH 04/40] ocfs2: move ip_last_trans to struct ocfs2_caching_info
We have the read side of metadata caching isolated to struct
ocfs2_caching_info, now we need the write side. This means the journal
functions. The journal only does a couple of things with struct inode.
This change moves the ip_last_trans field onto struct
ocfs2_caching_info as ci_last_trans. This field tells the journal
whether a pending journal flush is required.

[Ocfs2-devel] [PATCH 05/40] ocfs2: move ip_created_trans to struct ocfs2_caching_info
Similar ip_last_trans, ip_created_trans tracks the creation of a journal
managed inode. This specifically tracks what transaction created the
inode. This is so the code can know if the inode has ever been written
to disk.
This behavior is desirable for any journal managed object. We move it
to struct ocfs2_caching_info as ci_created_trans so that any object
using ocfs2_caching_info can rely on this behavior.

[Ocfs2-devel] [PATCH 06/40] ocfs2: Pass struct ocfs2_caching_info to the journal functions.
The next step in divorcing metadata I/O management from struct inode is
to pass struct ocfs2_caching_info to the journal functions. Thus the
journal locks a metadata cache with the cache io_lock function. It also
can compare ci_last_trans and ci_created_trans directly.
This is a large patch because of all the places we change
ocfs2_journal_access..(handle, inode, ...) to
ocfs2_journal_access..(handle, INODE_CACHE(inode), ...).

Joel Becker
2009-Feb-13 22:15 UTC
[Ocfs2-devel] [PATCH 07/40] ocfs2: Store the ocfs2_caching_info on ocfs2_extent_tree.
What do we cache? Metadata blocks. What are most of our non-inode metadata
blocks? Extent blocks for our btrees. struct ocfs2_extent_tree is the
main structure for managing those. So let's store the associated
ocfs2_caching_info there.
This means that ocfs2_et_root_journal_access() doesn't need struct inode
anymore, and any place that has an et can refer to et->et_ci instead of
INODE_CACHE(inode).

[Ocfs2-devel] [PATCH 08/40] ocfs2: Pass ocfs2_caching_info to ocfs2_read_extent_block().
extent blocks belong to btrees on more than just inodes, so we want to
pass the ocfs2_caching_info structure directly to
ocfs2_read_extent_block(). A number of places in alloc.c can now drop
struct inode from their argument list.

[Ocfs2-devel] [PATCH 14/40] ocfs2: Pass ocfs2_extent_tree to ocfs2_get_subtree_root()
Get rid of the inode argument. Use extent_tree instead. This means a
few more functions have to pass an extent_tree around.

[Ocfs2-devel] [PATCH 18/40] ocfs2: ocfs2_rotate_subtree_left() doesn't need struct inode.
It already has struct ocfs2_extent_tree, which has the caching info. So
we don't need to pass it struct inode.

[Ocfs2-devel] [PATCH 20/40] ocfs2: ocfs2_rotate_tree_left() no longer needs struct inode.
It already gets ocfs2_extent_tree, so we can just use that. This chains
to the same modification for ocfs2_remove_rightmost_path() and
ocfs2_rotate_rightmost_leaf_left().

[Ocfs2-devel] [PATCH 23/40] ocfs2: ocfs2_grow_branch() no longer needs struct inode.
It's not really using it other than to pass it to the subfunctions
ocfs2_shift_tree_depth(), ocfs2_find_branch_target(), and
ocfs2_add_branch(). They're not using it either, so they drop the
argument.

[Ocfs2-devel] [PATCH 26/40] ocfs2: Make truncating the extent map an extent_tree_operation.
ocfs2_remove_extent() wants to truncate the extent map if it's
truncating an inode data extent. But since many btrees can call that
function, let's make it an op on ocfs2_extent_tree. Other tree types
can leave it empty.

[Ocfs2-devel] [PATCH 34/40] ocfs2: Make extent map insertion an extent_tree_operation.
ocfs2_insert_extent() wants to insert a record into the extent map if
it's an inode data extent. But since many btrees can call that
function, let's make it an op on ocfs2_extent_tree. Other tree types
can leave it empty.

[Ocfs2-devel] [PATCH 39/40] ocfs2: __ocfs2_mark_extent_written() doesn't need struct inode.
We only allow unwritten extents on data, so the toplevel
ocfs2_mark_extent_written() can use an inode all it wants. But the
subfunction isn't even using the inode argument.

And if you really want to change it, it may be included in the patch you add INODE_CACHE I guess? Regards, Tao

Why we use "!time_after" and then check "!ret". I guess a "time_after" and "ret" is ok. Regards, Tao

[Ocfs2-devel] [PATCH 0/40] ocfs2: Detach ocfs2 metadata I/O from struct inode
Hi Joel, I deem that 1-3 is the same as the patch you sent to me several days ago. right? As I have reviewed them before, so didn't touch them this time. For 4~7, read them and like them. Just small comments ;) For 8~40, since they are just replacing parameters. Just skim them. anyway, They are cool and relieve me from my current work. Thank you very much. For all the patches, Acked-by: Tao Ma <tao.ma at oracle.com> Regards, Tao Joel Becker wrote:> The following series of patches attempts to detach metadata I/O from > struct inode.
