[PATCH] sys_pselect7 vs compat_sys_pselect7 uaccess error handling
758333458aa719bfc26ec16eafd4ad3a9e96014d fixes the not checked copy_to_user return value of compat_sys_pselect7. I ran into this too because of an old source tree, but my fix would look quite a bit different to Andi's fix. The reason is that the compat function IMHO should behave the very same as the non-compat function if possible. Since sys_pselect7 does not return -EFAULT in this specific case, change the compat code so it behaves like sys_pselect7.
