When using a large directory with large names, I noticed a 50% increase in the time it took to readdir the entire directory. With small names, the increase did not seem noticeable enough. Tested on a VM with bionic, no SMAP involved. Compared before memchr and after memchr. Need to compare before and after uaccess changes, both without SMAP and with SMAP.
