[PATCH 4.4 45/80] btrfs: dont leak ret from do_chunk_alloc

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Josef Bacik <josef@xxxxxxxxxxxxxx>

commit 4559b0a71749c442d34f7cfb9e72c9e58db83948 upstream.

If we're trying to make a data reservation and we have to allocate a
data chunk we could leak ret == 1, as do_chunk_alloc() will return 1 if
it allocated a chunk.  Since the end of the function is the success path
just return 0.
