I have this weird problem with Kconfig.
In fs/exofs/Kconfig I have:
# Library to be selected by users
config ORE
tristate
Then
config EXOFS_FS
tristate "exofs: OSD based file system support"
depends on SCSI_OSD_ULD
select ORE
help ...
So far so good. Choosing EXOFS_FS in xmenuconfig works fine as expected.
But now I add another user say: (It's more complicated but even below does
not work)
config NFS_FS
tristate "NFS client support"
depends on INET && FILE_LOCKING
select LOCKD
select SUNRPC
select NFS_ACL_SUPPORT if NFS_V3_ACL
select ORE
help ...
This does not work. The ORE is not compiled and MODPOST complains.
(Given EXOFS_FS is not selected since then it will work)
What am I doing wrong? Why can't I "select" in fs/nfs/Kconfig
an option in fs/exofs/Kconfig? What can I do different?
Thanks
Boaz

We're not given much to go by here. So I'll just mention the first thing
that I could think of: are you sure all NFS_FS's dependencies are met
(like NETWORK_FILESYSTEMS)?

fs/Makefile only visits fs/exofs if CONFIG_EXOFS_FS is set.

Bingo. Right on the money. With below patch it works. I'll think
about it some more and submit.
Thanks

exofs/ore: Select fs/exofs/ folder in Makefile also for ORE only compilation
If any thing from fs/exofs is set the ORE will be selected. So conditionally
include fs/exofs in fs/Makefile on ORE set and not EXOFS_FS

Note that changing it to obj-y is also valid. And perhaps more obvious.

Thanks. You read my thoughts. The naming would be off with my change.
I'll take your advise and send a patch to Al on Monday.
Cheers
