From 6859c3c6bb2b0f0e77ab764a61b474fb79f2550c Mon Sep 17 00:00:00 2001 From: Brendan Higgins Date: Wed, 4 Dec 2019 15:45:22 -0800 Subject: [PATCH] staging: exfat: fix multiple definition error of `rename_file' commit 1af73a25e6e7d9f2f1e2a14259cc9ffce6d8f6d4 upstream. `rename_file' was exported but not properly namespaced causing a multiple definition error because `rename_file' is already defined in fs/hostfs/hostfs_user.c: ld: drivers/staging/exfat/exfat_core.o: in function `rename_file': drivers/staging/exfat/exfat_core.c:2327: multiple definition of `rename_file'; fs/hostfs/hostfs_user.o:fs/hostfs/hostfs_user.c:350: first defined here make: *** [Makefile:1077: vmlinux] Error 1 This error can be reproduced on ARCH=um by selecting: CONFIG_EXFAT_FS=y CONFIG_HOSTFS=y Add a namespace prefix exfat_* to fix this error.
