[PATCH 4/4] jffs2: fix sparse warnings in gc.c

From: Harvey Harrison
Date: Fri Feb 15 2008 - 22:23:34 EST


fs/jffs2/gc.c:1147:29: warning: symbol 'jeb' shadows an earlier one
fs/jffs2/gc.c:1084:89: originally declared here

Add an sb_ prefix to the inner jeb variables as they are taken from
the super_blocks list.

It appears jffs2_garbage_collect_dnode never uses its jeb argument,
so as an alternative that could be dropped and the one caller adusted
then the inner variables would not need to be touched.
