A typical nfsd call trace is nfsd -> svc_process -> nfsd_dispatch -> nfsd3_proc_write -> nfsd_write ->nfsd_vfs_write -> vfs_writev These add up to over 300 bytes on the stack. Looking at each of these, I see that nfsd_write (which includes nfsd_vfs_write) contributes 0x8c to stack usage itself!! It turns out this is because it puts a 'struct iattr' on the stack so it can kill suid if needed. The following patch saves about 50 bytes off the stack in this call path.
