Hi all, Here are four patches against 3.17-rc4 to fix some minor problems in jbd2 and ext4. None of these four depend on each other; they fix separate small bugs. The first patch fixes the journal_checksum feature flag handling at mount time. This patch has been out for review on the list for a while. The second patch fixes external journal mounting so that the superblock checksum (of the ext. journal) is verified if metadata_csum is set. This is the same patch that has been out for review for a few days. The third patch fixes a journal_checksum_v3 replay bug -- if a block is in a transaction, and then later revoked and written into another transaction, and the block in the second transaction is corrupt, the journal would fail even to write the block from the first transaction. This would worsen the damage caused by a corrupt journal. The fourth bug fixes an inline_data bug where we would release a page but then keep using it, which resulted in complaints about freeing locked pages at umount time or strange system crashes. Patches are against 3.17-rc4, and have been xfstest'd and checked against debugfs creating test journals. There's still a hard to reproduce crash when ext4_destroy_inline_data_nolock tries to remove the inline data xattr from a corrupt inode, so we'll see if I can nail that one. Comments and questions are, as always, welcome. --D -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
