H A D | strnlen_user.c | a08c5356a3aaf638c41897ae4169de18db89595e Sat May 26 13:06:38 CDT 2012 Linus Torvalds <torvalds@linux-foundation.org> lib: add generic strnlen_user() function
This adds a new generic optimized strnlen_user() function that uses the <asm/word-at-a-time.h> infrastructure to portably do efficient string handling.
In many ways, strnlen is much simpler than strncpy, and in particular we can always pre-align the words we load from memory. That means that all the worries about alignment etc are a non-issue, so this one can easily be used on any architecture. You obviously do have to do the appropriate word-at-a-time.h macros.
