[Pvfs2-users] latest CVS and linux kernel 2.6.27

[Ryuta Suzuki]

Hi Phil,

I had grabbed the source from CVS repository. I updated the source and 
confirmed that it builds correctly. Thank you for the fix.

Just to make sure the patch work I downloaded the official releases, 
applying the patch to build kmod without success:

/home/ryuta/tmp/pvfs-2.7.1/src/kernel/linux-2.6/super.c:855: error: 
unknown field ‘put_inode’ specified in initializer
/home/ryuta/tmp/pvfs-2.7.1/src/kernel/linux-2.6/super.c:855: warning: 
initialization from incompatible pointer type
make[3]: *** [/home/ryuta/tmp/pvfs-2.7.1/src/kernel/linux-2.6/super.o] 
Error 1
make[2]: *** [_module_/home/ryuta/tmp/pvfs-2.7.1/src/kernel/linux-2.6] 
Error 2

If my memory serves me correctly, there must be another patches for the 
kernel module to accommodate the change in the linux kernel.

Anyway, thanks for the patch.
