From c4d7795fa55e897e16dcb2faa37c01a8216f19bd Mon Sep 17 00:00:00 2001 From: ChenXiaoSong Date: Fri, 17 Oct 2025 18:46:10 +0800 Subject: [PATCH] smb/server: fix return value of smb2_ioctl() [ Upstream commit 269df046c1e15ab34fa26fd90db9381f022a0963 ] __process_request() will not print error messages if smb2_ioctl() always returns 0. Fix this by returning the correct value at the end of function.
