Hi all,
A recent LLVM change [1] introduces a call to wcslen() in fs/smb/client/smb2pdu.c through UniStrcat() via alloc_path_with_tree_prefix(). Similar to the bcmp() and stpcpy() additions that happened in 5f074f3e192f and 1e1b6d63d634, add wcslen() to fix the linkage failure.

--- Changes in v2: - Refactor typedefs from nls.h into nls_types.h to make it safe to include in string.h, which may be included in many places throughout the kernel that may not like the other stuff nls.h brings in: https://lore.kernel.org/202503260611.MDurOUhF-lkp@intel.com/ - Drop libstub change due to the above change, as it is no longer necessary. - Move prototype shuffle of patch 2 into the patch that adds wcslen() (Andy) - Use new nls_types.h in string.{c,h} - Link to v1: https://lore.kernel.org/r/20250325-string-add-wcslen-for-llvm-opt-v1-0-b8f1e...
--- Nathan Chancellor (2): include: Move typedefs in nls.h to their own header lib/string.c: Add wcslen()
