Hello, I just noticed that 'tune2fs -l' did not returned a "lively" updated information regarding the free inodes count (looks like it's always correct after unmounting). It became suprising after an online resizing operation, where the total inode count was immediatly updated (grown in my case) but the free inode count was the same: one could deduce that suddenly a lot of

Can anyone tell me the history of CONFIG_EXT{2,3}_CHECK? There is code for a "check" option for mount if these options are enabled, but there's no way to enable them.

Has anyone tried LFS (ie >2G files support) and Ext3 together? Are there good reasons why this should/should not work? I see the RH enterprise kernel patch set specifically does not attempt both lfs and ext3, but the lfs patches themselves touch some reasonably localised parts of ext2, so I would hope (without having dived in there to test), that the ext3 changes would mirror that
