Name:mmdrop

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

Type:void

Parameter:

Type	Parameter	Name
struct mm_struct *	mm

48

If Value for the false possibility is greater at compile time(atomic_dec_and_test( & *@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.)) Then Called when the last reference to the mm* is dropped: either by a lazy thread or by* mmput. Free the page directory and the mm.

**Caller**
Name	Describe
__mmput
finish_task_switch	sh_task_switch - clean up after a task-switch*@prev: the thread we just switched away from
drop_futex_key_refs	Drop a reference to the resource addressed by a key.* The hash bucket spinlock must not be held. This is* a no-op for private futexes, see comment in the get* counterpart.
__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_unregister	This releases the mm_count pin automatically and frees the mm* structure if it was the last user of it. It serializes against* running mmu notifiers with SRCU and against mmu_notifier_unregister* with the unregister lock + SRCU
mmu_notifier_free_rcu
mmu_interval_notifier_remove	mmu_interval_notifier_remove - Remove a interval notifier@mni: Interval notifier to unregister This function must be paired with mmu_interval_notifier_insert()
scan_get_next_rmap_item
__ksm_exit
__khugepaged_exit
collect_mm_slot
bprm_mm_init	Create a new mm_struct and populate it with a temporary stack* vm_area_struct. We don't have enough context at this point to set the stack* flags, permissions, and offset, so we use temporary values. We'll update* them later in setup_arg_pages().
exec_mmap
userfaultfd_ctx_put	serfaultfd_ctx_put - Releases a reference to the internal userfaultfd* context.@ctx: [in] Pointer to userfaultfd context. The userfaultfd context reference must have been previously acquired either* with userfaultfd_ctx_get() or userfaultfd_ctx_fdget().
