linux-next: build failure after merge of the f2fs tree

Hi all,

After merging the f2fs tree, today's linux-next build (x86_64 allmodconfig) failed like this:

/tmp/next/build/fs/f2fs/inode.c:1065:6: error: call to undeclared function 'current_is_kswapd'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
1065 | if (current_is_kswapd()) {
| ^

Caused by commit

7451b3cd93b30 (f2fs: call __add_ino_entry out of the eviction path)

I have used the tree from next-20260810 instead.

My bad. Somehow I missed to add a header. Now, it should work.
