Hi Bruce, David,

After merging the nfsd and xfs trees, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

fs/xfs/linux-2.6/xfs_export.c: In function 'xfs_fs_nfs_commit_metadata':
fs/xfs/linux-2.6/xfs_export.c:230: error: 'XFS_LOG_FORCE' undeclared (first use in this function)
fs/xfs/linux-2.6/xfs_export.c:230: error: too many arguments to function '_xfs_log_force'

Caused by commit 978ebd97d1426d5708d3f353179ab81f191a7eeb
("xfs_export_operations.commit_metadata") from the nfsd tree interacting
with commit a14a348bff2f99471a28e5928eb6801224c053d8 ("xfs: cleanup up
xfs_log_force calling conventions") from the xfs tree.

I applied the following patch (which may not be correct) for today (and
can keep it as a merge fixup as necessary):

I was waiting for this email to come in. ;)

Yes, that is the correct fix. Thanks for that, Stephen. Consider it:

Reviewed-by: Dave Chinner <david(a)fromorbit.com>

Іt would be good if you could keep it as a merge fixup - we don't
really want to have to pull the -next NFS tree into the XFS tree or vice
versa until one or the other is upstream....

Cheers,

Dave.

Thanks for the confirmation.

Yep, no problem (I have a system that does that for me).
