Zhang Huan 6cba611e60 jbd2: fix potential memory leak on transaction commit ... There is potential memory leak of journal head in function jbd2_journal_commit_transaction. The problem is that JBD2 will not reclaim the journal head of commit record if error occurs or journal is abotred. I use the following script to reproduce this issue, on a RHEL6 system. I found it very easy to reproduce with async commit enabled. mount /dev/sdb /mnt -o journal_checksum,journal_async_commit touch /mnt/xxx echo offline > /sys/block/sdb/device/state sync umount /mnt rmmod ext4 rmmod jbd2 Removal of the jbd2 module will make slab complaining that "cache `jbd2_journal_head': can't free all objects".
