[PATCH v2 0/4] ext4, jbd2: improve aborting progress

["zhangyi (F)" <yi.zhang@huawei.com>]

Hi,

This series originally aim to fix ext4_handle_error() and ext4_abort()
cannot panic because of we invoke __jbd2_journal_abort_hard() when we
failed to submit commit record without setting JBD2_REC_ERR flag.

I add patch 1 and patch 4 to switch to use jbd2_journal_abort() and do
some cleanup job at this iteration as Jan suggested. I also add patch 3
to partially revert commit 818d276ceb8 "ext4: Add the journal checksum
feature" because it seems unnecessary, but I am not quite sure. please
revirew this series and give some suggestions.

Thanks,
Yi.
