This one isn't a result of kernel changes, but a result of bad debuginfo (or
systemtap's understanding of debuginfo). Systemtap doesn't think the inline
version of these functions have the '$task' parameter:
# stap -L 'module("nfs").function("nfs_read_done").*'
module("nfs").function("nfs_read_done@fs/nfs/proc.c:631").call $task:struct
rpc_task* $data:struct nfs_read_data*
module("nfs").function("nfs_read_done@fs/nfs/proc.c:631").inline $data:struct
nfs_read_data*
module("nfs").function("nfs_read_done@fs/nfs/proc.c:631").return $return:int
$task:struct rpc_task* $data:struct nfs_read_data*
