Subject: [PATCH 0/2] string.c: Add wcslen()
Date: Tue, 25 Mar 2025 08:45:17 -0700 [thread overview]
Message-ID: <20250325-string-add-wcslen-for-llvm-opt-v1-0-b8f1e2c17888@kernel.org> (raw)
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.
The second change is RFC because it makes the first change a little more
convoluted for the sake of making it externally available, which may or
may not be desirable. See the commit message for more details.
