I notice there's no change to write_leasetime(). That calls nfs4_reset_lease(), which seems to want to only be called when nfsd is not started (according to my reading of the comment preceding the function), and which uses the BKL to protect the variable user_lease_time. Perhaps that path should be changed to use the new nfsd_mutex also? Similarly with write_recoverydir(). That calls nfs4_reset_recoverydir() which uses client_mutex to protect user_recovery_dirname[], but that variable is only used during nfsd startup. Perhaps that path should use the new nfsd_mutex also? > diff --git a/fs/nfsd/nfssvc.c b/fs/nfsd/nfssvc.c > index 941041f..040b3c2 100644 > --- a/fs/nfsd/nfssvc.c > +++ b/fs/nfsd/nfssvc.c > @@ -53,11 +53,27 @@ > @@ -190,13 +206,14 @@ void nfsd_reset_versions(void) > @@ -223,7 +240,7 @@ int nfsd_create_serv(void) > @@ -282,6 +299,8 @@ int nfsd_set_nrthreads(int n, int *nthreads) > @@ -316,7 +335,6 @@ int nfsd_set_nrthreads(int n, int *nthreads) > @@ -325,7 +343,6 @@ int nfsd_set_nrthreads(int n, int *nthreads) > @@ -334,8 +351,8 @@ int > @@ -363,7 +380,7 @@ nfsd_svc(unsigned short port, int nrservs) > @@ -399,7 +416,7 @@ nfsd(struct svc_rqst *rqstp) > @@ -417,11 +434,13 @@ nfsd(struct svc_rqst *rqstp) > @@ -477,7 +496,7 @@ nfsd(struct svc_rqst *rqstp) > @@ -486,7 +505,7 @@ out: > All good. > diff --git a/net/sunrpc/svc.c b/net/sunrpc/svc.c > index 01c7e31..7bffaff 100644 > --- a/net/sunrpc/svc.c > +++ b/net/sunrpc/svc.c > @@ -461,7 +461,8 @@ svc_create_pooled(struct svc_program *prog, unsigned int bufsize, > @@ -578,9 +579,10 @@ out_enomem: > @@ -674,7 +676,7 @@ found_pool: > @@ -722,7 +724,8 @@ svc_set_num_threads(struct svc_serv *serv, struct svc_pool *pool, int nrservs) > All good. -- Greg Banks, P.Engineer, SGI Australian Software Group.
