Ouch! I totally forgot about that, sorry. I'll send out v3 tomorrow. And thanks for you reviews and suggestions. Cheers,

If a bad inode is found it will be deallocated. However, if the filesystem has quota enabled, the quota information isn't being updated accordingly. This issue was detected by running fstest ext4/019. This patch fixes the issue by decreasing the inode count from the quota and, if blocks are also being released, also subtract them as well.
