mainline inclusion from mainline-5.15-rc1 commit 8ef32967065737dac51974efae333436354bea0a category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/8ef329670657
-------------------------------
The smb_direct_alloc_sendmsg() function never returns NULL, it only returns error pointers so the check needs to be updated.
