Putting this into a separate patch makes the change non-bisectable since gcc will be checking against CONFIG_NFS_V3 but CONFIG_NFS_V3_MODULE is set. Should I have changed the CONFIG_ variables instead of using IS_ENABLED()? > > Why is it evaluating differently in the include file vs. the .c file? > Are we missing an include in nfs_fs.h? Good question. I don't see any reason that it would evaluate differently, but I'm compiling the .config attached to the initial email to try to figure it out. - Bryan > >>> >>> >>> >>>> -----Original Message----- >>>> From: Fengguang Wu [mailto:fengguang.wu@intel.com] >>>> Sent: Monday, July 30, 2012 10:43 PM >>>> To: Schumaker, Bryan >>>> Cc: kernel-janitors@vger.kernel.org; Myklebust, Trond; linux- >>>> nfs@vger.kernel.org >>>> Subject: [nfs:devel 46/51] fs/nfs/write.c:1592:5: error: redefinition of >>>> 'nfs_commit_inode' >>>> >>>> Hi Bryan, >>>> >>>> Kernel build failed on >>>> >>>> tree: git://git.linux-nfs.org/projects/trondmy/linux-nfs.git devel >>>> head: 5c13c9e1c15ee2ca9ab2b953224001af53d9be09 >>>> commit: 1c606fb74c758beafd98cbad9a9133eadeec2371 [46/51] NFS: Convert >>>> v3 into a module >>>> config: blackfin-BF533-EZKIT_defconfig (attached as .config) >>>> >>>> All related error/warning messages: >>>> >>>> fs/nfs/write.c:1592:5: error: redefinition of 'nfs_commit_inode' >>>> In file included from fs/nfs/write.c:19:0: >>>> include/linux/nfs_fs.h:547:1: note: previous definition of 'nfs_commit_inode' >>>> was here >>>> >>>> vim +1592 fs/nfs/write.c >>>> 1589 return status; >>>> 1590 } >>>> 1591 >>>>> 1592 int nfs_commit_inode(struct inode *inode, int how) >>>> 1593 { >>>> 1594 LIST_HEAD(head); >>>> 1595 struct nfs_commit_info cinfo; >>>> >>>> --- >>>> 0-DAY kernel build testing backend Open Source Technology Centre >>>> Fengguang Wu Intel Corporation >> >
