is anyone working on the above thing? It looks like an overkill to look up
the very same ~3 binary loaders for every do_exec() in a typical Linux
system, and wasting some ~300 usecs (or more) per lookup.

or does the new inode.c stuff solve this problem?

plus:

pc5829:~/trace/ktrace/samples$ grep get_empty_filp execve.out
Trace: c0127da8 <get_empty_filp+10/e4> (50.33)
Trace: c0127da8 <get_empty_filp+10/e4> (41.72)

thats 100 usecs more overhead per exec() ... get_empty_filp() sucks hard.
