| |
When printing the name of the current process, it will report an error: (gdb) p $lx_current().comm Python Exception <class 'gdb.error'> No symbol "current_task" in current context.: Error occurred in Python: No symbol "current_task" in current context.
Because the commit <e57ef2ed97c1> ("x86: Put hot per CPU variables into a struct") changed it.
