+Subject: kni: fix build with Linux 6.3
+Patch-mainline: yes
+Git-commit: 5f34cc454df420b9b2da8deb949fb76cba058b87
+References: kernel 6.3
+
+KNI calls `get_user_pages_remote()` API which is using `FOLL_TOUCH`
+flag, but `FOLL_TOUCH` is no more in public headers since v6.3,
+causing a build error.
+
+`FOLL_*` defines in Linux kernel first moved to another header [1],
+later some of them moved to memory subsystem internal header [2] for 6.3
+
+`get_user_pages_remote()` already sets `FOLL_TOUCH` internally,
+no need to set this flag externally anyway, moving flag from the call
+altogether.
+
+[1]
+Commit b5054174ac7c ("mm: move FOLL_* defs to mm_types.h")
+
+[2]
+Commit 2c2241081f7d ("mm/gup: move private gup FOLL_ flags to internal.h")
+
+Fixes: e73831dc6c26 ("kni: support userspace VA")
