函数名称：mpol_to_str - format a mempolicy structure for printing*@buffer: to contain formatted mempolicy string*@maxlen: length of @buffer*@pol: pointer to mempolicy to be formatted* Convert @pol into a string

函数原型：void mpol_to_str(char *buffer, int maxlen, struct mempolicy *pol)

返回类型：void

参数：

类型参数名称
char *buffer
intmaxlen
struct mempolicy *pol
2945  p等于buffer
2946  nodes等于NODE_MASK_NONE
2947  mode等于MPOL_DEFAULT
2948  flags等于0
2950  如果pol且pol不等于un-time system-wide default policy => local allocation且非See set_mempolicy() MPOL_F_* above 按位与Migrate On protnone Reference On Node 的值则
2951  mode等于See MPOL_* above
2952  flags等于See set_mempolicy() MPOL_F_* above
2956  当:mode恒等于MPOL_DEFAULT
2957  退出
2958  当:mode恒等于MPOL_PREFERRED
2959  如果flags按位与preferred local allocation 则mode等于MPOL_LOCAL
2961  否则The inline keyword gives the compiler room to decide to inline, or* not inline a function as it sees best( preferred , nodes)
2963  退出
2964  当:mode恒等于MPOL_BIND
2965  当:mode恒等于MPOL_INTERLEAVE
2966  nodes等于 interleave/bind
2967  退出
2968  默认
2969  WARN_ON_ONCE(1)
2970  snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@
2971  返回
2974  p加等于snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@
2976  如果flags按位与MPOL_MODE_FLAGS is the union of all possible optional mode flags passed to* either set_mempolicy() or mbind().则
2977  p加等于snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@
2982  如果flags按位与Flags for set_mempolicy 则p加等于snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@
2984  否则如果flags按位与MPOL_F_RELATIVE_NODES则p加等于snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@
2988  如果非nodes_empty(nodes)则p加等于格式化输出字符串
