类型参数名称
struct xarray *xa
466  XA_STATE() - Declare an XArray operation state.*@name: Name of this operation state (usually xas).*@array: Array to operate on.*@index: Initial index of interest.* Declare and initialise an xa_state on the stack.(xas, xa, 0)
470  以i小于200循环
471  以j小于2乘i加17循环
472  xas_set() - Set up XArray operation state for a different index
473  循环
477  当xas_nomem() - Allocate memory if needed.*@xas: XArray operation state.*@gfp: Memory allocation flags.* If we need to add new nodes to the XArray, we try to allocate memory* with GFP_NOWAIT while holding the lock, which will usually succeed.循环
480  xas_set() - Set up XArray operation state for a different index
481  循环
482  xas_lock( & xas)
483  xas_store() - Store this entry in the XArray
484  xas_unlock( & xas)
485  当xas_nomem() - Allocate memory if needed.*@xas: XArray operation state.*@gfp: Memory allocation flags.* If we need to add new nodes to the XArray, we try to allocate memory* with GFP_NOWAIT while holding the lock, which will usually succeed.循环
487  xas_lock( & xas)
488  xas_store() - Store this entry in the XArray
490  xas_set() - Set up XArray operation state for a different index
491  j等于i
493  XA_BUG_ON(xa, entry != xa_mk_index(j))
494  xas_store() - Store this entry in the XArray
495  j自加
497  xas_unlock( & xas)
498  XA_BUG_ON(xa, !xa_empty() - Determine if an array has any present entries.*@xa: XArray.* Context: Any context.* Return: %true if the array contains only NULL pointers.)
