This happens as follows: 1) Task A enters btrfs_ioctl_quota_rescan() -> btrfs_qgroup_rescan(); 2) Task B enters btrfs_quota_disable() and calls btrfs_qgroup_wait_for_completion(), which does nothing because at that point fs_info->qgroup_rescan_running is false (it wasn't set yet by task A); 3) Task B calls btrfs_free_qgroup_config() which starts freeing qgroups from fs_info->qgroup_tree without taking the lock fs_info->qgroup_lock; 4) Task A enters qgroup_rescan_zero_tracking() which starts iterating the fs_info->qgroup_tree tree while holding fs_info->qgroup_lock, but task B is freeing qgroup records from that tree without holding the lock, resulting in a use-after-free. Fix this by taking fs_info->qgroup_lock at btrfs_free_qgroup_config(). Also at btrfs_qgroup_rescan() don't start the rescan worker if quotas were already disabled.

So make sure we abort the transaction at __add_block_group_free_space() if it fails, which brings a couple benefits: 1) If some call chain never aborts the transaction, we avoid having some metadata inconsistency because BLOCK_GROUP_FLAG_NEEDS_FREE_SPACE is cleared when we enter __add_block_group_free_space() and therefore __add_block_group_free_space() is never called again to add the block group items to the free space tree, since the function is only called when that flag is set in a block group; 2) If the call chain already aborts the transaction, then we get a better trace that points to the exact step from __add_block_group_free_space() which failed, which is better for analysis. So abort the transaction at __add_block_group_free_space() if any of its steps fails.

The error comes from btrfs_iget_logging() <- btrfs_iget() <- btrfs_read_locked_inode(). The single caller of add_inode_ref(), replay_one_buffer(), ignores an -ENOENT error because it expects that error to mean only that a parent directory wasn't found and that is ok. Before commit 5f61b961599a ("btrfs: fix inode lookup error handling during log replay") we were converting any error when getting a parent directory to -ENOENT and any error when getting the current inode to -EIO, so our caller would fail log replay in case we can't find the current inode. After that commit however in case the current inode is not found we return -ENOENT to the caller and therefore it ignores the critical fact that the current inode was not found in the subvolume tree. Fix this by converting -ENOENT to 0 when we don't find a parent directory, returning -ENOENT when we don't find the current inode and making the caller, replay_one_buffer(), not ignore -ENOENT anymore.

Some systems, like the Radxa ROCK 5B are powered through USB-C without any backup power source and use a FUSB302 chip to do the PD negotiation. This means it is quite important to avoid hard resets, since that effectively kills the system's power-supply. I've found the following race condition while debugging unplanned power loss during booting the board every now and then: 1. lots of TCPM/FUSB302/PD initialization stuff 2. TCPM ends up in SNK_WAIT_CAPABILITIES (tcpm_set_pd_rx is enabled here) 3. the remote PD source does not send anything, so TCPM does a SOFT RESET 4. TCPM ends up in SNK_WAIT_CAPABILITIES for the second time (tcpm_set_pd_rx is enabled again, even though it is still on) At this point I've seen broken CRC good messages being send by the FUSB302 with a logic analyzer sniffing the CC lines. Also it looks like messages are being lost and things generally going haywire with one of the two sides doing a hard reset once a broken CRC good message was send to the bus. I think the system is running into a race condition, that the FIFOs are being cleared and/or the automatic good CRC message generation flag is being updated while a message is already arriving. Let's avoid this by caching the PD RX enabled state, as we have already processed anything in the FIFOs and are in a good state. As a side effect that this also optimizes I2C bus usage :) As far as I can tell the problem theoretically also exists when TCPM enters SNK_WAIT_CAPABILITIES the first time, but I believe this is less critical for the following reason: On devices like the ROCK 5B, which are powered through a TCPM backed USB-C port, the bootloader must have done some prior PD communication (initial communication must happen within 5 seconds after plugging the USB-C plug). This means the first time the kernel TCPM state machine reaches SNK_WAIT_CAPABILITIES, the remote side is not sending messages actively. On other devices a hard reset simply adds some extra delay and things should be good afterwards.
