[JFFS2][XATTR] Remove jffs2_garbage_collect_xattr(c, ic)
Remove jffs2_garbage_collect_xattr(c, ic). jffs2_garbage_collect_xattr_datum/ref() are called from gc.c directly. In original implementation, jffs2_garbage_collect_xattr(c, ic) returns with holding a spinlock if 'ic' is inode_cache. But it returns after releasing a spinlock if 'ic' is xattr_datum/ref. It looks so confusable behavior. Thus, this patch makes caller manage locking/unlocking. [5/10] jffs2-xattr-v5.1-05-update_xattr_gc.patch Signed-off-by: KaiGai Kohei <kaigai@ak.jp.nec.com>
