Under include/linux, some files will be created such like autoconf.h,
version.h, and compile.h. The timestamps of the dir will be updated too.
So aufs will copyup the dir.

This log is produced by a cron job, instead of 'ls /usr/src/linux/include'.
The cron job issued
- mkdir
- open(O_TRUNC) by makewhatis
and aufs handles them with internal copyup.

I don't thik they were operating /usr/src/linux/inlcude, so there was no
log produced by your 'ls'.
