From 38f4f01f8fe7aba72f858fd6faa0126edc645fe1 Mon Sep 17 00:00:00 2001 From: Pavel Boldin Date: Mon, 23 Mar 2015 14:53:45 +0200 Subject: [PATCH] vhost: fix file struct leakage Due to increased `struct file's reference counter subsequent call to `filp_close' does not free the `struct file'. Prepend `fput' call to decrease the reference counter.
