The code has been tested in a ring together with other HSR nodes running unchanged code, on both avr32 and x86_64. There should only be one minor change in behaviour from a user perspective: * Anyone using the Netlink HSR_C_GET_NODE_LIST message to dump the internal node database will notice that the database now also contains the self node. All patches pass 'checkpatch.pl --ignore CAMELCASE --max-line-length=83 --strict' with only CHECKs, each of which have been deliberately left in place. The final code passes sparse checks with no output. ==================== Signed-off-by: David S. Miller --- 92a129dafc27f300451fb8faead99736ea16f898
