Subject: [PATCH] isofs: avoid unused function warning
Date: Wed, 19 Nov 2014 15:11:24 +0100 [thread overview]
Message-ID: <1744765.FITJHBjs5L@wuerfel> (raw)
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")
