Functionally it looks fine. As you say, it all looks like context
changes. Arguably code like this

current->flags &= ~PF_FSTRANS

could use tsk_restore_flags instead() even though it should never be
necessary as PF_FSTRANS would not be set on function entry. However,
it would set up a depedency between the patch sets that is undesirable.
If both sets get merged then it might make sense as a cleanup to use
tsk_restore_flags() but not until then.

Thanks Stephen.
