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.
|
|
|
|

|
|
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")
