Subject: [PATCH 0/4] ext[34]: Fix deadlock between truncate and get_block()

  Hello,

  below come patches that fix lockdep annotations in JBD / JBD2 so that we are
properly warned about possibly deadlocks caused by a transaction being
restarted. Further follow patches that fix a possible deadlock between truncate
and get_blocks() in ext3/ext4 which Ted spotted. I'm quite confident in the ext3
fix but the ext4 fix definitely needs a serious review because there are
cosiderably more places working with the extent tree. I *think* ext4 patch is
fine as I argue in the changelog and I went through all places acquiring
i_data_sem but I might have missed some interaction / callsite...
