函数名称:Build the Merkle tree for the given inode using the given parameters, and* return the root hash in @root_hash.* The tree is written to a filesystem-specific location as determined by the* ->write_merkle_tree_block() method
函数原型:static int build_merkle_tree(struct inode *inode, const struct merkle_tree_params *params, u8 *root_hash)
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
struct inode * | inode | |
const struct merkle_tree_params * | params | |
u8 * | root_hash |
123 | 如果i_size恒等于0则 |
125 | memset(root_hash, 0, same as hash_alg->digest_size ) |
126 | 返回:0 |
129 | pending_hashes等于开辟内存 |
131 | 如果非pending_hashes或非req则转到:out |
139 | blocks等于i_size加size of data and tree blocks 减1右移log2(block_size) 位 |
141 | 以level小于等于umber of levels in Merkle tree 循环 |
142 | err等于build_merkle_tree_level(inode, level, blocks, params, pending_hashes, req) |
150 | err等于0 |
151 | out : |
152 | 释放内存 |
153 | 归零并释放数据结构请求 |
154 | 返回:err |
