Subject: [PATCH 0/3] xfs: fix inode use-after-free during log recovery
Date: Tue, 21 Apr 2020 19:08:07 -0700	[thread overview]
Message-ID: <158752128766.2142108.8793264653760565688.stgit@magnolia> (raw)

Hi all,

Fix a use-after-free during log recovery of deferred operations by
creating explicit freeze and thaw mechanisms for deferred ops that were
created while processing intent items that were recovered from the log.
While we're at it, fix all the bogosity around how we gather up log
intents during recovery and actually commit them to the filesystem.

If you're going to start using this mess, you probably ought to just
pull from my git trees, which are linked below.

This is an extraordinary way to destroy everything.  Enjoy!
Comments and questions are, as always, welcome.
