[ibm-acpi-devel] [PATCH 17/22] thinkpad_acpi: Replace strnicmp with strncasecmp
The kernel used to contain two functions for length-delimited,
case-insensitive string comparison, strnicmp with correct semantics
and a slightly buggy strncasecmp. The latter is the POSIX name, so
strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper
for the new strncasecmp to avoid breaking existing users.
To allow the compat wrapper strnicmp to be removed at some point in
the future, and to avoid the extra indirection cost, do
s/strnicmp/strncasecmp/g.

As of this morning I still see them as independent functions in lib/string.c. -- Darren Hart Intel Open Source Technology Center -- Slashdot TV. Video for Nerds.

I thought it had made it to linux-next, but should have double-checked (and included the 3.18 info in the email); sorry. http://thread.gmane.org/gmane.linux.kernel/1775150/focus=1775152 Rasmus -- Slashdot TV.
