Subject: [PATCH v4 3/9] Uprobe: Change set_orig_insn definition
Date: Wed, 20 Jun 2018 09:26:23 +0530 [thread overview]
Message-ID: <20180620035629.7844-4-ravi.bangoria@linux.ibm.com> (raw)
In-Reply-To: <20180620035629.7844-1-ravi.bangoria@linux.ibm.com>
Instead of arch_uprobe, pass uprobe object to set_orig_insn(). We
need this in later set of patches.
