Subject: [PATCH v5 04/10] Uprobe: Change set_orig_insn definition
Date: Thu, 28 Jun 2018 10:52:03 +0530	[thread overview]
Message-ID: <20180628052209.13056-5-ravi.bangoria@linux.ibm.com> (raw)
In-Reply-To: <20180628052209.13056-1-ravi.bangoria@linux.ibm.com>

Instead of arch_uprobe, pass uprobe object to set_orig_insn(). We
need this in later set of patches.
