函数名称:gen_pool_add_owner- add a new chunk of special memory to the pool*@pool: pool to add new memory chunk to*@virt: virtual starting address of memory chunk to add to pool*@phys: physical starting address of memory chunk to add to pool*@size: size in bytes of
函数原型:int gen_pool_add_owner(struct gen_pool *pool, unsigned long virt, phys_addr_t phys, size_t size, int nid, void *owner)
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
struct gen_pool * | pool | |
unsigned long | virt | |
phys_addr_t | phys | |
size_t | size | |
int | nid | |
void * | owner |
186 | nbits等于size右移 minimum allocation order 位 |
187 | nbytes等于sizeof(structgen_pool_chunk)加BITS_TO_LONGS(nbits)乘sizeof(long) |
190 | chunk等于vzalloc_node(nbytes, nid) |
191 | 如果此条件成立可能性小(为编译器优化)(chunk == NULL)则返回:负ENOMEM |
198 | atomic_long_set( & avail, size) |
200 | 加自旋锁 |
201 | 添加RCU保护项 |
202 | 自旋锁解锁 |
204 | 返回:0 |
