Subject: [PATCH] ext4: add __user decoration to calls of copy_{from,to}_user()
This quiets the sparse noise:
warning: incorrect type in argument 2 (different address spaces)
expected void const [noderef] <asn:1>*from
got struct fstrim_range *<noident>
warning: incorrect type in argument 1 (different address spaces)
expected void [noderef] <asn:1>*to
