stable inclusion from stable-v4.19.270 commit 707682dbab5b61d6b7a95b05491b476510aeeb64 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6DPF8 CVE: NA
--------------------------------
commit a152d05ae4a71d802d50cf9177dba34e8bb09f68 upstream.
If smb311 posix is enabled, we send the intended mode for file creation in the posix create context. Instead of using what's there on the stack, create the mfsymlink file with 0644.
