SubjectRe: current->state after kmalloc
In article <16Xt8Y-1SQ44eC@fwd04.sul.t-online.com> you wrote:

> what is current->state after kmalloc ?

undefined. If kmalloc slept and you survived (due to setting
TASK_INTERRUPTIBLE that's not guaranteed) then it'll most likely be
TASK_RUNNING.
If you depend on this your kernel code is broken in that has subtle
dependencies on unspecified behavior and will break whenever kmalloc changes
internal behavior.
