Re: [PATCH mm-hotfixes-unstable v18 00/14] khugepaged: add mTHP collapse support

Not sure if already addressed for v19 but I just tried building a kernel in
mm-unstable and saw this (clang 22.1.6):

mm/khugepaged.c:1357:6: warning: variable 'pte' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized]

Is this already addressed in v19/review here? If not could you please address it.
