Mainline Linux tree for various devices, only for fun :)
952bd3db0d
Running generic/019 with qgroups on the scratch device enabled is almost guaranteed to trigger the BUG_ON in btrfs_free_tree_block. It's supposed to trigger only on -ENOMEM, in reality, however, it's possible to get -EIO from btrfs_qgroup_trace_extent_post. This function just finds the roots of the extent being tracked and sets the qrecord->old_roots list. If this operation fails nothing critical happens except the quota accounting can be considered wrong. In such case just set the INCONSISTENT flag for the quota and print a warning, rather than killing off the system. Additionally, it's possible to trigger a BUG_ON in btrfs_truncate_inode_items as well.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
