linux-next: build failure after merge of the vfs-brauner tree

Hi all,

After merging the vfs-brauner tree, today's linux-next build (arm64 allnoconfig) failed like this:

/tmp/next/build/fs/sysfs/mount.c: In function 'sysfs_init_fs_context':
/tmp/next/build/fs/sysfs/mount.c:75:37: error: implicit declaration of function 'to_net_ns'; did you mean 'get_net_ns'? [-Wimplicit-function-declaration]
75 | struct net *netns = to_net_ns(ns);
| ^~~~~~~~~ get_net_ns
/tmp/next/build/fs/sysfs/mount.c:75:37: error: initialization of 'struct net *' from 'int' makes pointer from integer without a cast [-Wint-conversion]

Caused by commit

9a8098b1d5023 (kernfs: pass struct ns_common instead of const void * for namespace tags)

I have used the version from next-20260408 instead.
