But, it also requeues the block for later attempts. Since these are hard RPC tasks, if the client we're calling back goes unresponsive the GRANT_MSG callbacks can stack up in the RPC queue. Fix this by making server-side RPC clients default to soft RPC tasks. lockd requeues the block anyway, so this should be OK. Signed-off-by: Jeff Layton Signed-off-by: J.
