[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).
