Hi Chris,
Looks like you missed Miao update (on 17 Jul) to back out the bad
patch (below), and your integration branch (published on 25 Jul)
still contains the same.
[PATCH 2/2] Btrfs: fix wrong total device counter after removing a seed
device
You should remove it.
Simple test cases on your integration branch (like btrfs dev del OR
btrfs/003) is failing due to this and I (+ others would) spend some
time digging it out
Miao,
If it helps -
cur_devices in the loop is null.
BUG: unable to handle kernel NULL pointer dereference at 0000000000000050
IP: [<ffffffffa00a8fc0>] btrfs_rm_device+0x4c0/0x860 [btrfs]
cur_devices = root->fs_info->fs_devices;
do {
cur_devices->total_devices--;
cur_devices = cur_devices->seed;
} while (device->fs_devices != cur_devices);
PS: I didn't find the follow-up patch in the mailing list,
did I missing anything ?
Thanks, Anand

Hi everyone,
I've pushed out my current integration branch. It does have a few of
Miao Xie's patches missing because there were some rejects. I think
this was just because some things got pulled in out of order, and I'll
get it fixed up.
Also missing is Mark's quota snapshot deletion fixes. They were
crashing during btrfs/011 with CONFIG_DEBUG_PAGE_ALLOC on. We'll get
that nailed down.
integration is subject to rebasing, so please treat it more like a patch
queue. It is very lightly tested, the goal is just to show which
patches are already applied and which ones are still pending.
Thanks!
