I_DIRTY_DATASYNC -- arla requires 2.4 kernel?

[Harald Barth]

What Arla version are we talking about? I guess 0.35.something.

For xfs (in current renamed nnpfs) the _kernel_ include files are the
relevant ones as xfs is linked with the kernel. These are normally
found in /usr/src/linux-versionnumber/include/ and if constants are
missing, to support that kernel version this should be fixed in xfs.

Unfortunately for you, arla support for 2.2.x kernels is fainting as
noone in the development team is running such an old kernel. So it
will probably not get fixed. The README in the distribution should
reflect this.

Currently the efforts are concentrated to get the 0.36 release out of
the door. This has been complicated by the syscall magic that is
needed with the newest RH and 2.4.2x kernels. 

I you choose to upgrade to 2.4.x, 2.4.18 is a kernel version that I
have used a lot and seems to work fine with Arla.

Harald.
