[PATCH 0/2] btrfs: fix use-after-free in btrfs_encoded_read_endio

[Johannes Thumshirn <jth@kernel.org>]

Shinichiro reported a occassional memory corruption in our CI system with
btrfs/248 that lead to panics. He also managed to reproduce this
corruption reliably on one host. See patch 1/2 for details on the
corruption and the fix, patch 2/2 is a cleanup Damien suggested on top of
the fix to make the code more obvious.

Mark, I've tried your test tool for the encoded read io_uring path, but didn't
succeed building it. Can you please have a look at these patches with an
io_uring hat on?
