| |
2.6.32-stable review patch. If anyone has any objections, please let us know.
------------------
From: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
commit ebddd63b74dcf1cb676d14328d5852f1fee19a8a upstream.
When truncating an UBI volume, UBI should allocates a PEB-sized buffer but does not release it, which leads to memory leaks. This patch fixes the issue.
