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

 



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

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

From: "nikolay@xxxxxxxxxx" <nikolay@xxxxxxxxxx>

commit b6a5a7b9a528a8b4c8bec940b607c5dd9102b8cc upstream.

While enslaving a new device and after IFF_BONDING flag is set, in case
of failure it is not stripped from the device's priv_flags while
cleaning up, which could lead to other problems.
Cleaning at err_close because the flag is set after dev_open().

v2: no change
