Both lockd and (in the nfsv4 case) nfsd enforce a "grace period" after reboot, during which clients may reclaim locks from the previous server instance, but may not acquire new locks. Currently the lockd and nfsd enforce grace periods of different lengths. This may cause problems when we reboot a server with both v2/v3 and v4 clients. For example, if the lockd grace period is shorter (as is likely the case), then a v3 client might acquire a new lock that conflicts with a lock already held (but not yet reclaimed) by a v4 client. This patch calculates a lease time that lockd and nfsd can both use. Signed-off-by: Marc Eshel <eshel@almaden.ibm.com> Signed-off-by: J.
