If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 819f47cefce3f9a56997ba9f6c05882744bb281b Author: Wang Ming <machel@xxxxxxxx> Date: Sun Dec 31 16:12:51 2023 +0900 ksmbd: Fix unsigned expression compared with zero [ Upstream commit 0266a2f791294e0b4ba36f4a1d89b8615ea3cac0 ] The return value of the ksmbd_vfs_getcasexattr() is signed. However, the return value is being assigned to an unsigned variable and subsequently recasted, causing warnings. Use a signed type.
