[PATCH] reiserfs: reset errval after initializing bitmap cache
Callers after reiserfs_init_bitmap_cache() expect errval to contain -EINVAL until much later. If a condition fails before errval is reset later, reiserfs_fill_super() will mistakenly return 0, causing an Oops in do_add_mount(). This patch resets errval to -EINVAL after the call. I view this as a temporary fix and real error codes should be used throughout reiserfs_fill_super().
