For the stable backport, drop the original header cleanup because the stable-only __KERNEL__ guard makes it conflict and the target does not touch or depend on those declarations. Instead, carry only a behavior-preserving local snapshot of mnt_cifs_flags in cifs_setattr_nounix(); the target patch refers to that snapshot in its new setuid/setgid condition.

For the stable backport, drop the original smb2proto.h cleanup because the
stable header has gained and changed declarations that make the scripted
rewrite conflict, while the target does not touch or depend on the header.
Instead, carry only behavior-preserving context preparation in inode.c: use
the type-safe kmalloc_obj() spelling and the existing local sbflags snapshot,
and brace the adjacent else-if.  This allows both target hunks to apply
cleanly without pre-applying the target's behavioral change.
