The patch titled Subject: scripts/gdb/linux/tasks.py: fix get_thread_info has been removed from the -mm tree. Its filename was scripts-gdb-fix-get_thread_info.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------ From: Xi Kangjie imxikangjie@gmail.com Subject: 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 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}
