В ядре Linux устранена следующая уязвимость:
btrfs: fix reservation leak in some error paths when inserting inline extent
If we fail to allocate a path or join a transaction, we return from
__cow_file_range_inline() without freeing the reserved qgroup data,
что приводит к утечке. Fix this by ensuring we call btrfs_qgroup_free_data()
в таких случаях.

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix reservation leak in some error paths when inserting inline extent If we fail to allocate a path or join a transaction, we return from __cow_file_range_inline() without freeing the reserved qgroup data, resulting in a leak. Fix this by ensuring we call btrfs_qgroup_free_data() in such cases.
