get_task

函数名称：get_task_mm - acquire a reference to the task's mm* Returns %NULL if the task has no mm. Checks PF_KTHREAD (meaning* this kernel workthread has transiently adopted a user mm with use_mm,* to do its AIO) is not set and if so returns a reference to it, after

函数原型：struct mm_struct *get_task_mm(struct task_struct *task)

返回类型：struct mm_struct

mm_access
ptrace_access_vm	Access another process' address space via ptrace.* Source/target buffer must be kernel space,* Do not walk the page table directly, use get_user_pages
getrusage
update_tasks_nodemask	pdate_tasks_nodemask - Update the nodemasks of tasks in the cpuset.@cs: the cpuset in which each task's mems_allowed mask needs to be changed Iterate through each task of @cs updating its mems_allowed to the* effective cpuset's
cpuset_attach
trace_user_stack_print	TRACE_USER_STACK
perf_event_addr_filters_apply	Update event's address range filters based on the* task's existing mappings, if any.
access_process_vm	Access another process' address space.* - source/target buffer must be kernel space
