[PATCH] ufs: fix hang during `rm'
This fixes the code like this: bh = sb_find_get_block (sb, tmp + j); if ((bh && DATA_BUFFER_USED(bh)) || tmp != fs32_to_cpu(sb, *p)) { retry = 1; brelse (bh); goto next1; } bforget (bh); sb_find_get_block() ordinarily returns a buffer_head with b_count>=2, and this code assume that in case if "b_count>1" buffer is used, so this caused infinite loop. (akpm: that is-the-buffer-busy code is incomprehensible. Good riddance. Use of block_truncate_page() seems sane).
