Hi folks,
As I mentioned in the in-kernel libxfs reowrk thread, there's a
problem with the libxfs code being dependent on the struct
xfs_mount, which is defined externally to libxfs.
The series stemmed from that as a way of working out the issues with
untangling the circular dependency mess. Essentially all the da code
is dependent on the struct xfs-mount for directory and attribute
tree configuration - block sizes, merge thresholds, etc. These all
need to be defined and managed by the libxfs code itself, and the
external code should just manage it.
So, this patchset removes one of the dependencies from the da code
by adding a geometry structure to the xfs_da_args that contains all
the necessary information from the struct xfs_mount. In doing this
abstraction, I realised that this is exactly the abstraction needed
to do per-inode directory block size configuration rather than have
it be fixed for the entire filesystem by the superblock. So the
patch set also sets the ground work for that.
It also opens some other interesting avenues - the directory
geometry is really just a specialised data fork allocation policy
structure. I'll leave the reader to follow that to it's logical
conclusion....
Now, this patchset is currently only compile tested - if you try to
run it, it will eat all your Precious' and then ask "Please, Sir,
can I have some more?". There are things that I've noticed in later
patches that need fixing in earlier patches and I've just left them
with an XXX in place, so there's no need to tell me that work needs
to be done to fix this ;)
I am posting it, however, to demonstrate the process which I think
we need to take to properly abstract the core XFS code from both the
kernel glue layer and the userspace layer. I'm looking for early
feedback for this in the context of the libxfs-in-kernel branch I
posted a couple of days ago. I don't want to get 90% into a
restructure and then have people say "No, this is wrong!".
Eventually, I'd like to have the libxfs code be completely
indepenent of the struct xfs_mount, and the external struct
xfs_mount just hold a bunch of structures it passes to the libxfs
code. It'll take quite a bit of work to get there, but if I'm going
to be using libxfs as the core infrastructure of a smart block
device, I don't want to carry an xfs_mount around at all....
So, flames, comments, deep thoughts, ponderings, straight jackets,
and so on are all welcome! just don't try to run the code ;)
Cheers,
Dave.

All of the verification checks of magic numbers are now done by
verifiers, so ther eis no need to check them again once the buffer
has been successfully read. If the magic number is bad, it won't
even get to that code to verify it so it really serves no purpose at
all anymore. Remove it.

The directory code has a dependency on the struct xfs_mount to
supply the directory block geometry. Block size, block log size,
and other parameters are pre-caclulated in the struct xfs_mount or
access directly from the superblock embedded in the struct
xfs_mount.
Extract all of this geometry information out of the struct xfs_mount
and superblock and place it into a new struct xfs_da_geometry
defined by the directory code. Allocate and initialise it at mount
time, and attach it to the struct xfs_mount so it canbe passed back
into the directory code appropriately rather than using the struct
xfs_mount.

Because they aren't actually part of the on-disk format, and so
shouldn't be in xfs_da_format.h.

They are just simple wrappers around xfs_dir2_byte_to_db(), and
we've already removed one usage earlier in the patch set. Kill
the reset before we start removing the xfs_mount from conversion
functions.

From: Dave Chinner <dchinner@redhat.com>
There are many places in the directory code were we don't pass the
args into and so have to extract the geometry direct from the mount
structure. Push the args or the geometry into these leaf functions
so that we don't need to grab it from the struct xfs_mount.
This, in turn, brings use to the point where directory geometry is
no longer a property of the struct xfs_mount; it is not a global
property anymore, and hence we can start to consider per-directory
configuration of physical geometries.
Start by converting the xfs_dir_isblock/leaf code - pass in the
xfs_da_args and convert the readdir code to use xfs_da_args like
the rest of the directory code to pass information around.

From: Dave Chinner @ 2014-05-08 8:19 UTC (permalink / raw)
To: xfs
From: Dave Chinner <dchinner@redhat.com>
We don't pass the xfs_da_args or the geometry all the way down to
the directory buffer logging code, hence we have to use
mp->m_dir_geo here. Fix this to use the geometry passed via the
xfs_da_args, and convert all the directory logging functions for
consistency.

From: Dave Chinner @ 2014-05-08 8:19 UTC (permalink / raw)
To: xfs
From: Dave Chinner <dchinner@redhat.com>
Right now the geometry source for directory and attributes is the
struct xfs_mount - it's global. There's nothing stopping use from
having per-inode directory geometry or (in future) attribute
geometry.
To move the dependency on the struct xfs_mount out from the da_args
setup code, add a geometry pointer to the struct xfs_inode_fork.
This can be set up for directories when the inode is instantiated,
either from the xfs_mount or from the on-disk inode configuration
(think extent size hints for directories).
While this might seem wasteful to burn a pointer in the data fork
for all files, consider that the geometry information
for data allocation can be abstracted from the xfs_mount in exactly
the same way as has been done for the directory geometry.
Effectively it's a hook to carry allocation policy around in....
So, add the geometry pointer to the inode fork, and initialise is
appropriately and use it for all the directory and attribute
operation setup instead ofthe xfs_mount version.

A definitively NAK to bloating the inode without actually making
use of this. I can see where you might want to go with this, but
until we actuall support different dir block sizes per inodes or
similar, and it actually proves to be useful this is not something
that should go in.
The rest of the series looks okay as long as we don't touch the inode,
but I'll have to do a slightly more detailed review.

Yeah, that's fine. it's more just a demonstration of where this
takes us. That said, it's pretty trivial to add directory block size
config to the on-disk format. We can use the high bits of the extent
size hint field so we don't take any more sapce.
That is, di_extsize is a 32 bit field that holds a log2 value of the
hint. The hint is set in bytes via a u32 in the ioctl structure,
so at most can have a value that represents an extent size of 4GB.
That's an ondisk value range of 0-25, which only requires the lower
5 bits of the di_extsize field on disk.
For directories, we currently set the value only with the
XFS_XFLAG_EXTSZINHERIT flag to indicate that the di_extsize hint
field contains the value new children should inherit. If we allow
the XFS_XFLAG_EXTSZ to also be set and use the upper
16 bits of the di_extsize field to indicate the directory block
size, then we have a method for configuring per-directory block
sizes without needing to add any new userspace interfaces....

I need to clean it up and make it work properly before that. Wait
for the resend. ;)
Cheers,
Dave.
