Subject: [boot hang] rb_consumer: page allocation failure: order:0,
mode:0x10d0
Greetings,
I got the below dmesg and the first bad commit is
commit 294e30fee35d3151d100cfe59e839c2dbc16a374
Author: Josef Bacik <jbacik@...ionio.com>

Btrfs: add tests for find_lock_delalloc_range
So both Liu and I made huge messes of find_lock_delalloc_range trying to fix
stuff, me first by fixing extent size, then him by fixing something I broke and
then me again telling him to fix it a different way. So this is obviously a
candidate for some testing. This patch adds a pseudo fs so we can allocate fake
inodes for tests that need an inode or pages. Then it addes a bunch of tests to
make sure find_lock_delalloc_range is acting the way it is supposed to. With
this patch and all of our previous patches to find_lock_delalloc_range I am sure
it is working as expected now. Thanks,
