[Impact]

In btrfs_get_root_ref in fs/btrfs/disk-io.c in the Linux kernel through
6.7.1, there can be an assertion failure and crash because a subvolume can
be read out too soon after its root item is inserted upon subvolume
creation.

[Fix]

Mantic: Clean cherry-pick.
Jammy: Mantic patch applied cleanly.

[Test Case]

Compile and boot tested.

[Where problems could occur]

This affects those who use a kernel 6.7.1 and older and make subvolumes
for btrfs.

Qu Wenruo (1):
  btrfs: do not ASSERT() if the newly created subvolume already got read
