remove_free_dqentry

函数名称：Remove given block from the list of blocks with free entries

函数原型：static int remove_free_dqentry(struct qtree_mem_dqinfo *info, char *buf, uint blk)

返回类型：int

参数：

类型	参数	名称
struct qtree_mem_dqinfo *	info
char *	buf
uint	blk

135

tmpbuf等于getdqbuf(Space usable in block for quota data )

136

dh等于buf

137

nextblk等于le32_to_cpu(Number of next block with free entry )

138

prevblk等于le32_to_cpu(Number of previous block with free entry )

141

如果非tmpbuf则返回:负ENOMEM

143

如果nextblk则

144

err等于read_blk(info, nextblk, tmpbuf)

145

如果err小于0则转到:out_buf

147

Number of previous block with free entry 等于Number of previous block with free entry

149

err等于write_blk(info, nextblk, tmpbuf)

150

如果err小于0则转到:out_buf

153

如果prevblk则

154

err等于read_blk(info, prevblk, tmpbuf)

155

如果err小于0则转到:out_buf

157

Number of next block with free entry 等于Number of next block with free entry

159

err等于write_blk(info, prevblk, tmpbuf)

160

如果err小于0则转到:out_buf

162

否则

163

First block with free entry 等于nextblk

164

mark_info_dirty(Sb quota is on , Quota type )

166

释放内存

167

Number of next block with free entry 等于Number of previous block with free entry 等于cpu_to_le32(0)

169

如果write_blk(info, blk, buf)小于0则quota_error(Sb quota is on , "Can't write block (%u) with free entries", blk)

172

返回:0

173

out_buf :

174

释放内存

175

返回:err
