error: ‘struct lov_user_mds_data_v2’ has no member named ‘lmd_st’ with Lustre 2.13

Hi!

I got the following error when trying to compile mpifileutils 0.10 with Lustre 2.13.0:

Start in src/common/mfu_flist_walk.c at lustre_mds_stat and inspect the Lustre headers provided by Lustre 2.13. Reproduce the reported CMake build with ENABLE_LUSTRE=ON. Done means mpifileutils compiles successfully with the Lustre 2.13 client without the missing lmd_st member error.
