[lustre-devel] [PATCH 453/622] lustre: uapi: fix building fail against Power9 little endian

[James Simmons]

From: Gu Zheng <gzheng at ddn.com>

We use "%ll[dux]" for __u64 variable as an input/output modifier,
this may cause building error on some architectures which use "long"
for 64-bit types, for example, Power9 little endian.
Here add necessary typecasting (long long/unsigned long long) to
make the build correct.
