Andrew,
I noticed this follow up patch did not make it's way into -mm and
subsequently to 2.6.15-rc2. The uid_t and gid_t fields appear to present
a 32/64-bit userspace/kernel problem for some archs.
This patch addresses the problem by fixing the size to the largest
size for uid_t/gid_t used in the kernel. This preserves the total size of
the event structure while ensuring that the layouts of the ID change event
match in 32 and 64-bit kernels and applications.
Please apply.
