Known Issues in 2.2.0:

LU-1188 Panics can occur running sanity test while running with kernel debug options turned on
LU-1191 Due to a known NFS-related bug in the kernel - https://bugzilla.kernel.org/show_bug.cgi?id=38572 - users wanting to re-export Lustre via NFS should apply the kernel patch for this issue
