Subject: [PATCH] uprobes/tracing: Ensure inode != NULL in
 create_trace_uprobe()

probe_event_enable/disable() check tu->inode != NULL at the start.
This is ugly, if igrab() can fail create_trace_uprobe() should not
succeed and "postpone" the failure.

And S_ISREG(inode->i_mode) check added by d24d7dbf is not safe.

Note: alloc_uprobe() should probably check igrab() != NULL as well.
