Subject: [PATCH 2/7] x86/ftrace: Fix use of flags in ftrace_replace_code()
Date: Tue, 18 Jun 2019 20:17:01 +0530	[thread overview]
Message-ID: <34eec86399b310a5567ee37d62a24aae0b72ffc5.1560868106.git.naveen.n.rao@linux.vnet.ibm.com> (raw)
In-Reply-To: <cover.1560868106.git.naveen.n.rao@linux.vnet.ibm.com>

In commit a0572f687fb3c ("ftrace: Allow ftrace_replace_code() to be
schedulable), the generic ftrace_replace_code() function was modified to
accept a flags argument in place of a single 'enable' flag. However, the
x86 version of this function was not updated. Fix the same.

Fixes: a0572f687fb3c ("ftrace: Allow ftrace_replace_code() to be schedulable")
