Rafael J. Wysocki d5d8c5976d freezer: do not send signals to kernel threads ... The freezer should not send signals to kernel threads, since that may lead to subtle problems. In particular, commit b74d0deb96 has changed recalc_sigpending_tsk() so that it doesn't clear TIF_SIGPENDING. For this reason, if the freezer continues to send fake signals to kernel threads and the freezing of kernel threads fails, some of them may be running with TIF_SIGPENDING set forever. Accordingly, recalc_sigpending_tsk() shouldn't set the task's TIF_SIGPENDING flag if TIF_FREEZE is set. Signed-off-by: Rafael J.
