Date: Fri, 01 Apr 2011 20:03:58 +0530 [thread overview] Message-ID: <20110401143358.15455.53804.sendpatchset@localhost6.localdomain6> (raw) In-Reply-To: <20110401143223.15455.19844.sendpatchset@localhost6.localdomain6> On the first probe insertion, copy the original instruction and opcode. If multiple vmas map the same text area corresponding to an inode, we only need to copy the instruction just once. The copied instruction is further copied to a designated slot on probe hit. Its also used at the time of probe removal to restore the original instruction. opcode is used to analyze the instruction and determine the fixups. Determining fixups at probe hit time would result in doing the same operation on every probe hit. Hence Instruction analysis using the opcode is done at probe insertion time.
