net/smc: longer delay when freeing client link groups
Client link group creation always follows the server linkgroup creation. If peer creates a new server link group, client has to create a new client link group. If peer reuses a server link group for a new connection, client has to reuse its client link group as well. To avoid out-of-sync conditions for link groups a longer delay for for client link group removal is defined to make sure this link group still exists, once the peer decides to reuse a server link group. Currently the client link group delay time is just 10 jiffies larger than the server link group delay time. This patch increases the delay difference to 10 seconds to have a better protection against out-of-sync link groups. Signed-off-by: Ursula Braun <ubraun@linux.ibm.com> Signed-off-by: David S.
