size等于count减done

9201

如果size大于等于WRITE_BUFSIZE则size等于WRITE_BUFSIZE减1

9204

如果copy_from_user(kbuf, buffer + done, size)则

9205

ret等于负EFAULT

9206

转到:out

9208

kbuf[size]等于'\0'

9209

buf等于kbuf

9210

循环

9211

tmp等于strchr - Find the first occurrence of the character c in the string s.*@s: the string to be searched*@c: the character to search for

9212

如果tmp则

9213

tmp等于'\0'

9214

size等于tmp减buf加1

9215

否则

9216

size等于strlen - Find the length of a string*@s: The string to be sized

9217

如果done加size小于count则

9218

如果buf不等于kbuf则退出

9221

打印警告信息("Line length is too long: Should be less than %d\n", WRITE_BUFSIZE - 2)

9223

ret等于负EINVAL

9224

转到:out

9227

done加等于size

9230

tmp等于strchr - Find the first occurrence of the character c in the string s.*@s: the string to be searched*@c: the character to search for

9232

如果tmp则tmp等于'\0'

9235

ret等于trace_run_command(buf, createfn)

9236

如果ret则转到:out

9238

buf加等于size

9240

当done小于count 循环
