The above commit is still in your tree which makes it unbuildable since the interface it uses does not exist in your tree (are you testing it?). $ git grep -w largest_zero_folio vfs-brauner/vfs.all vfs-brauner/vfs.all:fs/iomap/direct-io.c: struct folio *zero_folio = =3D largest_zero_folio(); $ git grep -w largest_zero_folio mm-unstable/mm-unstable=20 mm-unstable/mm-unstable:block/blk-lib.c: struct folio *zero_folio = =3D largest_zero_folio(); mm-unstable/mm-unstable:include/linux/huge_mm.h: * largest_zero_folio - Get= the largest zero size folio available mm-unstable/mm-unstable:include/linux/huge_mm.h:static inline struct folio = *largest_zero_folio(void) Please fix this up - maybe just drop/revert that commit until it is sorted out. --=20 Cheers, Stephen Rothwell --Sig_/_XGv/ViooFqSz+Tvec0=/hd Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAmimUjEACgkQAVBC80lX 0GwOwQf/fS0Ys23NuamjtfD1bM84E0WR5vME/ui/gqncY7Vfj+5Hk078+1sRJna8 Bu4MdhZEbJ500u96j2otbMCOfcdFQBGYZi62+BAtotUkYJZ3ZuIi5kMfKVPRBIOh lieY0Sixtg0uLiM1o9oOoF/fA2Y13InutAjmOTmpgUnLCs4tbZxX/PEaNauq7kQp iI3zfgdS8RgQgJpgPONwyvjoNw3gGq54rPQFkGpwsNiDCj6C0ioxmZUDcvTuWAyC 05q/u+cGG1AFcXHoqhTnCzM7O0n//UQXc/nrE71Q5U71aNT0Tcxxb2T02RnQAkTB fdrbEeGCT5dekGdbTyRYU2qRfD2nRA== =tDLA -----END PGP SIGNATURE----- --Sig_/_XGv/ViooFqSz+Tvec0=/hd--
