Subject: scripts/gdb: correct indentation in get_current_task
Date: Sun, 26 Feb 2023 22:05:59 -0600

Patch series "scripts/gdb: Support getting current task struct in UML",
v3.

A running x86 UML kernel reports with architecture "i386:x86-64" as it is
a sub-architecture.  However, a difference with bare-metal x86 kernels is
in how it manages tasks and the current task struct.  To identify that the
inferior is a UML kernel and not bare-metal, check for the existence of
the UML specific symbol "cpu_tasks" which contains the current task
struct.


This patch (of 3):

There is an extra space in a couple blocks in get_current_task.  Though
python does not care, let's make the spacing consistent.  Also, format
better an if expression, removing unneeded parenthesis.
