Subject: Re: [RFC PATCH -v2 6/9] ext4: Call journal commit callback without
	holding j_list_lock

I suggest adding the following description and to change the prefix to
be jbd2, not ext4, since the change applies 100% to jbd2 code (and so
it could potentially apply to ocfs2 if they decide to use this
callback, for example).

jbd2: Call journal commit callback without holding j_list_lock

Avoid freeing the transaction in __jbd2_journal_drop_transaction() so
the journal commit callback can run without holding j_list_lock, to
avoid lock contention on this spinlock.
