scripts/gdb/linux/tasks.py: fix get_thread_info
Since kernel 4.9, the thread_info has been moved into task_struct, no longer locates at the bottom of kernel stack. See commits c65eacbe290b ("sched/core: Allow putting thread_info into task_struct") and 15f4eae70d36 ("x86: Move thread_info into task_struct"). Before fix: (gdb) set $current = $lx_current() (gdb) p $lx_thread_info($current) $1 = {flags = 1470918301} (gdb) p $current.thread_info $2 = {flags = 2147483648} After fix: (gdb) p $lx_thread_info($current) $1 = {flags = 2147483648} (gdb) p $current.thread_info $2 = {flags = 2147483648} Link: http://lkml.kernel.org/r/20180118210159.17223-1-imxikangjie@gmail.com Fixes: 15f4eae70d36 ("x86: Move thread_info into task_struct") Signed-off-by: Xi Kangjie <imxikangjie@gmail.com> Acked-by: Jan Kiszka <jan.kiszka@siemens.com> Acked-by: Kieran Bingham <kbingham@kernel.org> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
