Subject: [PATCH] btrfs: return error pointer from alloc_test_extent_buffer
Callers of alloc_test_extent_buffer have not correctly interpreted the
return value as error pointer, as alloc_test_extent_buffer should behave
as alloc_extent_buffer. The self-tests were unaffected but
btrfs_find_create_tree_block could call both functions and that would
cause problems up in the call chain.

Few conflicts on the backport mostly due to message formatting (such as
9e3d9f8462ef ("btrfs: tests: use standard error message after extent
buffer allocation failure") ). I've fixed them up and queued for
4.19-4.4.
