Hi,

I am trying to get the DMAPI stuff going on xfs again. I last played
with it back in the 2.4.25 kernel and it worked great.
I now want to resume the work that I started back then, but are unable
to get the dmapi to work on any recent kernel. I tried both 2.4.33 from
the cvs and 2.6.17 from the cvs. (Both checked out on 2006-08-26).

2.4.33 was unable to compile.

I then did: (which I know is not a proper fix, but I was desperate to
get it to compile and was'nt too concerned about atime problems)

It did compile then, but could not mount a filesystem with dmapi.
Unfortunatedly I did'nt save the kernel output.

The 2.6.17 compiled cleanly, but also could not mount.
I got the following dump:

I used "mount /dev/md1 -o dmapi,mtpt=/mnt /mnt" to try and mount the
filesystem in all the cases (which worked great back in 2.4.25).


I would appreciate any help.

I am trying to get the DMAPI stuff going on xfs again. I last played 
with it back in the 2.4.25 kernel and it worked great.
I now want to resume the work that I started back then, but are unable

the cvs and 2.6.17 from the cvs. (Both checked out on 2006-08-26).

2.4.33 was unable to compile.

I then did: (which I know is not a proper fix, but I was desperate to 
get it to compile and was'nt too concerned about atime problems)

It did compile then, but could not mount a filesystem with dmapi.
Unfortunatedly I did'nt save the kernel output.

The 2.6.17 compiled cleanly, but also could not mount.
I got the following dump:

I used "mount /dev/md1 -o dmapi,mtpt=/mnt /mnt" to try and mount the 
filesystem in all the cases (which worked great back in 2.4.25).


I would appreciate any help.
