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. > Looks like the IS_ENABLED() switch got pushed to the next patch for V3 in include/linux/nfs_fs.h. Want me to resend the patches? I took another look at how IS_ENABLED() is defined, and it'll work if I do the switch in the patch before I turn everything into separate modules if you want me to resend everything. > - Bryan > >> >>>> >>>> >>>> >>>>> -----Original Message----- >>>>> From: Fengguang Wu [mailto:fengguang.wu@xxxxxxxxx] >>>>> Sent: Monday, July 30, 2012 10:43 PM >>>>> To: Schumaker, Bryan >>>>> Cc: kernel-janitors@xxxxxxxxxxxxxxx; Myklebust, Trond; linux- >>>>> nfs@xxxxxxxxxxxxxxx >>>>> 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 <wfg@xxxxxxxxxxxxxxx> Intel Corporation >>> >> > -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
