Proto:static inline void mmgrab(struct mm_struct *mm)

Type:void

Parameter:

Type	Parameter	Name
struct mm_struct *	mm

36

atomic_inc( & *@mm_count: The number of references to &struct mm_struct * (@mm_users count as 1). * Use mmgrab()/mmdrop() to modify. When this drops to 0, the * &struct mm_struct is freed.)

**Caller**
Name	Describe
cpu_init	pu_init() initializes state that is per-CPU. Some data is already* initialized (naturally) in the bootstrap process, such as the GDT* and IDT. We reload them nevertheless, this function acts as a* 'CPU state barrier', nothing should get across.
exit_mm	Turn us into a lazy TLB process if we* aren't already..
context_switch	ext_switch - switch to the new MM and the new thread's register state.
sched_init
futex_get_mm
mark_oom_victim	mark_oom_victim - mark the given task as OOM victim@tsk: task to mark Has to be called with oom_lock held and never after* oom has been disabled already.* under task_lock or operate on the current).
__oom_kill_process
use_mm	se_mm* Makes the calling kernel thread take on the specified* mm context.* (Note: this routine is intended to be called only* from a kernel thread context)
__mmu_notifier_register	Same as mmu_notifier_register but here the caller must hold the mmap_sem in* write mode. A NULL mn signals the notifier is being registered for itree* mode.
