| |
NFS currently bugs out on kernels with a page size of 64KB. The reason is a mismatch between RPCSVC_MAXPAGES and a calculation in svc_init_buffer(). I'm not entirely certain which calculation is the right one, but if I understand the code correctly, RPCSVC_MAXPAGES is right and svc_init_buffer() is wrong. The patch below fixes the latter.
If the patch looks right, could you make sure it finds its way into Linus' tree?
Thanks,
