Revision 7ca2f234404e738cc807ed87c43f9932513bc8c6 authored by Arnd Bergmann on 19 November 2014, 14:11:24 UTC, committed by Al Viro on 19 November 2014, 18:09:37 UTC
With the isofs_hash() function removed, isofs_hash_ms() is the only user of isofs_hash_common(), but it's defined inside of an #ifdef, which triggers this gcc warning in ARM axm55xx_defconfig starting with v3.18-rc3: fs/isofs/inode.c:177:1: warning: 'isofs_hash_common' defined but not used [-Wunused-function] This patch moves the function inside of the same #ifdef section to avoid that warning, which seems the best compromise of a relatively harmless patch for a late -rc. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Fixes: b0afd8e5db7b ("isofs: don't bother with ->d_op for normal case") Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
