Hi Chuck,

There are new sparse warnings (likely a true locking bug) show up in

tree:   git://git.linux-nfs.org/projects/trondmy/linux-nfs.git nfs-for-bryan
head:   6a1a1e34dc55f17e7bd260809207442dbb7a0296
commit: 6a1a1e34dc55f17e7bd260809207442dbb7a0296 [100/100] SUNRPC: Add rpcauth_list_flavors()

All sparse warnings:

  net/sunrpc/auth_gss/gss_mech_switch.c:143:21: sparse: symbol '_gss_mech_get_by_name' was not declared. Should it be static?
  net/sunrpc/auth_gss/gss_mech_switch.c:208:21: sparse: symbol '_gss_mech_get_by_pseudoflavor' was not declared. Should it be static?
+ net/sunrpc/auth_gss/gss_mech_switch.c:252:5: sparse: context imbalance in 'gss_mech_list_pseudoflavors' - wrong count at exit
