Makes sense, but could we just get this out of include/linux entirely,
and into fs/nfsd/?
$ git grep -l '^#include <linux/nfsd/stats.h>'
fs/nfsd/nfssvc.c
fs/nfsd/stats.c
include/linux/nfsd/nfsd.h
So the only user outside of fs/nfsd/ is nfsd.h. I doubt it really needs
it. And nfsd.h is included a lot of places it needn't be too:
$ git grep -l '^#include <linux/nfsd/nfsd.h>'
arch/parisc/kernel/sys_parisc32.c
arch/s390/kernel/compat_linux.c
arch/s390/kernel/compat_linux.h
arch/sparc64/kernel/sys_sparc32.c
Those includes are unnecessary.
fs/compat.c
That too, I think.
fs/lockd/svc4proc.c
fs/lockd/svcproc.c
Those might need it (though they shouldn't also need stats.h). Etc.
fs/nfsctl.c
fs/nfsd/auth.c
fs/nfsd/export.c
fs/nfsd/lockd.c
fs/nfsd/nfs2acl.c
fs/nfsd/nfs3acl.c
fs/nfsd/nfs3proc.c
fs/nfsd/nfs3xdr.c
fs/nfsd/nfs4callback.c
fs/nfsd/nfs4proc.c
fs/nfsd/nfs4recover.c
fs/nfsd/nfs4state.c
fs/nfsd/nfs4xdr.c
fs/nfsd/nfscache.c
fs/nfsd/nfsctl.c
fs/nfsd/nfsfh.c
fs/nfsd/nfsproc.c
fs/nfsd/nfssvc.c
fs/nfsd/nfsxdr.c
fs/nfsd/stats.c
fs/nfsd/vfs.c
