Followinng up my message of a couple of days ago on profiling, here are

What one would like to gather is for each SMB op requested, the total
system call time spent on that OP.
At the moment, all that goes through the VFS stuff, and although the VFS
stuff is slightly broken as well (it should record nested values or
separate values), it would be nice if it was recorded against both system
call time in total and against the SMB op that invoked it.

1. A separate set of system call counts and times for each SMB op as well
as the total that are currently kept.
