Hi all
I think there is a problem about journal in ext3.
in linux-2.6.17/include/linux/ext3_jbd.h
/* Define the number of blocks we need to account to a transaction to
* modify one block of data.
*
* We may have to touch one inode, one bitmap buffer, up to three
* indirection blocks, the group and superblock summaries, and the data
* block to complete the transaction. */
#define EXT3_SINGLEDATA_TRANS_BLOCKS 8U
The indirection blocks' modification also need their bitmap buffer and the
group summaries be modified, I think. So the block count should be 8U + 3*2;
Additionally, the journal operations in namei.c or inode.c also have the
problem like that.
Am I right? or misunderstand?
cheers, zhangjw
