Hi Wendy,

doesn't this patch require porting to the STABLE branch as well?

I can't find a direct_IO_cluster_locking on vanilla kernels so i assume this is
a specific redhat extension.

if i understand the problem right, shouldn't the stable branch get the patch
using blockdev_direct_IO_own_locking ?

TIA
Fabio
