Question. What is success criteria for jffs2_garbage_collect_pass() execution?

Why asking? In the case described above jffs2_find_gc_block() fails to
find erase block for garbage collection but falling into
jffs2_flush_wbuf_pad(c) which produces amount of erasing blocks. So
jffs2_garbage_collect_pass() sees no single block for garbage
collection, but filesystem still recieves fresh erasing blocks upon
execution.

Is it success or failure? Theoretically.

Thanks,
Alexander
