From: Mike Marshall <hubcap@xxxxxxxxxxxx> The deamon through which the kernel module communicates with the userspace part of Orangefs, the "client-core", sends initialization data to the kernel module with ioctl. The initialization data was built by the client-core in a 2k buffer and copy_from_user'd into a 1k buffer in the kernel module. When more than 1k of initialization data needed to be sent, some was lost, reducing the usability of the control by which debug levels are set. This patch sets the kernel side buffer to 2K to match the userspace side...
