Subject: [PATCH 3/4] kernel/fork: use vfree() instead of vfree_atomic() to free thread stack
Date: Thu, 30 Mar 2017 13:27:18 +0300 [thread overview]
Message-ID: <20170330102719.13119-3-aryabinin@virtuozzo.com> (raw)
In-Reply-To: <20170330102719.13119-1-aryabinin@virtuozzo.com>
vfree() can be used in any atomic context now, thus there is no point
in using vfree_atomic().
This reverts commit 0f110a9b956c ("kernel/fork: use vfree_atomic()
to free thread stack")
