Description

In the Linux kernel, the following vulnerability has been resolved:

xfs: don't let memory failures leak blocks and kill repairs

LOLLM complains that a memory allocation failure in
xrep_newbt_add_blocks results in online repair leaking blocks that were
previously allocated to write a new btree, but the problem is worse than
that -- a limitation of the codebase is that the callers cannot undo the
transaction /and/ return the error -- either you undo all changes and
commit the transaction, or you error out and the filesystem goes down.

However, the new btree space reservation object isn't that big (~48
bytes). Let's just do a NOFAIL allocation and the problem goes away.
