Hi, folks.

I don't mean to anger, but does anyone have any idea how I can overcome this 
issue?  Besides the above, I tried to recompile the kernel to export the 
__d_path() function, and got this:

address@hidden dazuko-2.3.4]# patch /lib/modules/`uname -r`/build/fs/dcache.c 
patch_dpath.diff
patch: **** Can't find file /lib/modules/2.6.18-53.1.6.el5/build/fs/dcache.c : 
No such file or directory

Yet:

address@hidden dazuko-2.3.4]# uname -a
Linux hingham2 2.6.18-53.1.6.el5 #1 SMP Wed Jan 23 11:30:20 EST 2008 i686 
athlon i386 GNU/Linux

So, I know the kernel is correctly specified in the command, and I know that 
the kernel source is installed.  However, a search for dcache.c turns up 
nothing.

So, I can't install dazuko using reqular means, or with 
the --disable-local-dpath" and/or "--disable-chroot-support" switches, or by 
recompiling the kernel.  If I do " ./configure --enable-syscalls 
--mapfile=/boot/System.map-2.6.1853.1.6.el5", it compiles, but when I install 
the dazuko module, the system hangs.

Am I sol here?

Thanks.

Dimitri
