URL: https://github.com/llvm/llvm-project/commit/2ca6fc34fc08eaadb0f287a7f1b33bc1de4d1bd6 DIFF: https://github.com/llvm/llvm-project/commit/2ca6fc34fc08eaadb0f287a7f1b33bc1de4d1bd6.diff LOG: [clang] [DirectoryWatcher] Remove leading \\?\ from GetFinalPathNameByHandleW This is needed for the paths to work when using forward slashes; this fixes the DirectoryWatcherTests unit tests. Also allocate missing space for the null terminator, which seems to have been missing all along (writing the terminator out of bounds).
