Unfortunately there\nare two SMP-related problems with this approach. First, a task running on\nanother CPU may be updating its flags while the freezer attempts to set\nPF_FREEZE for it and this may leave the task\u0027s flags in an inconsistent\nstate. Second, there is a potential race between freeze_process() and\nrefrigerator() in which freeze_process() running on one CPU is reading a\ntask\u0027s PF_FREEZE flag while refrigerator() running on another CPU has just\nset PF_FROZEN for the same task and attempts to reset PF_FREEZE for it. If\nthe refrigerator wins the race, freeze_process() will state that PF_FREEZE\nhasn\u0027t been set for the task and will set it unnecessarily, so the task\nwill go to the refrigerator once again after it\u0027s been thawed.\n\nTo solve first of these problems we need to stop using PF_FREEZE to tell\ntasks that they should go to the refrigerator. Instead, we can introduce a\nspecial TIF_*** flag and use it for this purpose, since it is allowed to\nchange the other tasks\u0027 TIF_*** flags and there are special calls for it.\n\nTo avoid the freeze_process()-refrigerator() race we can make\nfreeze_process() to always check the task\u0027s PF_FROZEN flag after it\u0027s read\nits \"freeze\" flag. We should also make sure that refrigerator() will\nalways reset the task\u0027s \"freeze\" flag after it\u0027s set PF_FROZEN for it.\n\nSigned-off-by: Rafael J.
