Subject: Re: [PATCH] Fix EXT4FS_DEBUG build: use ext4_free_blks_count and
	%u instead of %lu


在 2009-01-23五的 00:52 -0200，Thadeu Lima de Souza Cascardo写道：
> When bg_free_blocks_count was renamed to bg_free_blocks_count_lo in

> ext4_free_blks_count.
> 
> Another commit, 498e5f24, also did not change everything needed under
