Subject: ext4: add __user decoration to calls of copy_{from,to}_user()
X-Git-Tag: v3.2-rc1~85^2~43
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e6705f7c255d1ffae7cd161d0b657296f4dd62fd;p=thirdparty%2Fkernel%2Flinux.git

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
   got struct fstrim_range *<noident>
