[PATCH 4.9 003/118] 9p/net: fix memory leak in p9_client_create

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

 



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

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

From: zhengbin <zhengbin13@xxxxxxxxxx>

commit bb06c388fa20ae24cfe80c52488de718a7e3a53f upstream.

If msize is less than 4096, we should close and put trans, destroy
tagpool, not just free client. This patch fixes that.
