Both nfsd and nfsv4-callback take a temporary reference to the svc_serv while calling svc_set_num_threads() to stop the last thread. lockd does not. This extra reference prevents the scv_serv from being freed when the last thread drops its reference count. This is not currently needed for lockd as the svc_serv is not accessed after the last thread is told to exit. However a future patch will require svc_exit_thread() to access the svc_serv after the svc_put() so it will need the code that calls svc_set_num_threads() to keep a reference and keep the svc_serv active. So copy the pattern from nfsd and nfsv4-cb to lockd, and take a reference around svc_set_num_threads(.., 0) Reviewed-by: Jeff Layton <jlayton@kernel.org> Tested-by: Jeff Layton <jlayton@kernel.org> Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Chuck Lever <chuck.lever@oracle.com> |
