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'.
