Oops, This build error log is genereated when building ext4 filesystem as a module and this is originated from that "percpu_free_rwsem()" function was not defined as an exported function. Could I define the "percpu_free_rwsem()" function as an exported function directly in this patch? Or do I have to request the maintainer of percpu_rwsem to do this? Thank you in advance. :-) > url: https://github.com/0day-ci/linux/commits/Daeho-Jeong/ext4-handle-unwritten-or-delalloc-buffers-before-enabling-per-file-dat> a-journaling/20160229-075117 > base: https://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git dev > config: x86_64-randconfig-s2-02290828 (attached as .config) > reproduce: > # save the attached .config to linux build tree > make ARCH=x86_64 > All errors (new ones prefixed by >>): > >> ERROR: "percpu_free_rwsem" [fs/ext4/ext4.ko] undefined!��.n��������+%������w��{.n�����{�����ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
