This is on top of Benny's conversion (SQUASHME):
pnfsd-exofs: convert to v3.1 ORE
This patch does 3 things:
1. Most of the code is doing the conversion to the new ORE code.
2. Upstream exofs patch has removed the sbi->data_map
member see:
exofs: Remove unused data_map member from exofs_sb_info
3. A *creds variable was set to NULL and kfreed at end, which is
a fallout of some passed, "Convert osd XDR layout encoding"
patch.

Avoid the 32 bit -1 group_depth problem by using the
group_width=0 case
This is a bug introduced by the previous patch "Convert to ORE 3.1"
Where the data_map member was removed from exofs_sb_info

Do to patch:
exofs: Rename struct ore_components comps => oc
Fix it here as well.
Do to patch:
ore/exofs: Change the type of the devices array (API change)
* Comply with the API change of the ore_components device table
type.
* Use the container_of macro to access the extra exofs device info.
.e.g the device_id

The number of devices in a system can get big real fast.
Just last week we tested with a x64 osd system. The layout
buffer sent from the pnfs client has space for about 21
components.
Serve out a single group segment at a time, and only send
a group-full of devices. Which is usually not bigger then 8
or 9.

Hmm, I get the following compile error.
Is there a chance you have some local changes in your tree you haven't committed
to 6127dbde SQUASHME pnfsd-exofs: Serve out a single group layout at a time
fs/exofs/export.c: In function ‘exofs_layout_get’:
fs/exofs/export.c:143:2: warning: passing argument 3 of ‘ore_calc_stripe_info’ makes integer from pointer without a cast [enabled by default]
include/scsi/osd_ore.h:174:6: note: expected ‘u64’ but argument is of type ‘struct ore_striping_info *’
fs/exofs/export.c:143:2: error: too few arguments to function ‘ore_calc_stripe_info’
include/scsi/osd_ore.h:174:6: note: declared here
Since si.length is not in use in exofs_layout_get
This fix should work, right?
