Hi,<br>
<br>
I want to know whether lttng trace data will provide mapping from file names to corresponding inode.<br>
<br>
I refered some data parsed by babeltrace,and found that internal kernel tracepoints like writeback_dirty_inode_start、jbd2_submit_inode_data and lttng_statedump_vm_map can provide inode parameter.But I don’t know the meaning of these tracepoints mentioned above, and it seems to have little to do with the mapping we need.I want to know which tracepoint will record the mapping.<br>
<br>
In addition, I found the get_inode_from_fd() function at <a href="https://github.com/lttng/lttng-modules/blob/master/src/probes/lttng-uprobes.c" target="_blank">lttng-uprobes.c</a>.It seems to provide some hints, can this function provide the mapping information we want?If so, how should I use it to get the data.<br>
<br>
<p>
Looking forward to your reply.
