map_id_range_down

函数名称：map_id_range_down_base - Find idmap via binary search in static extent array.* Can only be called if number of mappings is equal or less than* UID_GID_MAP_MAX_BASE_EXTENTS.

函数原型：static struct uid_gid_extent *map_id_range_down_base(unsigned extents, struct uid_gid_map *map, unsigned int id, unsigned int count)

返回类型：struct uid_gid_extent

参数：

类型	参数	名称
unsigned	extents
struct uid_gid_map *	map
unsigned int	id
unsigned int	count

277

id2等于id加count减1

280

以idx小于extents 循环

281

first等于first

282

last等于first加count减1

283

如果id大于等于first且id小于等于last且id2大于等于first且id2小于等于last则返回:extent[idx]

287

返回:NULL
