With gcc-12.2.1-clang-15.0.2-glibc-2.36-binutils-2.39-kernel-6.0.5-sanitized we get a warning about path.dentry being used uninitialized: fs/fs.c:1978:43: warning: 'path.dentry' may be used uninitialized -Wmaybe-uninitialized] I can't see how this can really happen. gcc seems to think that this sequence used in lookup_fast() can result in returning 0: if (IS_ERR(dentry)) return PTR_ERR(dentry); This shouldn't happen. Silence the warning by initializing 'path'.
