Subject: [Patch] statistics: fix cpu hot unplug related memory leak
Date: Tue, 10 Apr 2007 17:54:59 +0200 [thread overview]
Message-ID: <1176220499.5572.19.camel@dix> (raw)
In case of CPU hotunplug statistics might have leaked some memory
(lists of struct statistic_entry_sparse, about 32 byte each, freed
by statistic_sparse_reset()).
Patch is against 2.6.21-rc6-mm1.
