hi, all
you know in the linux userspace , i can compile and run the following program to get the name or inode number of the files in the /bin directory.
i want to know how to do this in linux kernelspace ? thank you very much!

struct dirent *entry;
struct stat statbuf;
if((dp = opendir(dir)) == NULL){
fprintf(stderr,"cannot open directory: %s\n",dir);
return;
}
chdir(dir);
while((entry = readdir(dp)) != NULL){
lstat(entry->d_name,&statbuf);
if(S_ISDIR(statbuf.st_mode)){
if(strcmp("..",entry->d_name) == 0||
strcmp(".",entry->d_name) == 0)
continue;
printf("%*s%s/\n",depth,"",entry->d_name);
printdir(entry->d_name,depth+4);
}
else printf("%*s%s\n",depth,"",entry->d_name);
}
chdir("..");
closedir(dp);
}
int main(){
printdir("/bin",0); }

Hi,
Please see the following helpful reference topic:
http://kernelnewbies.org/FAQ/WhyWritingFilesFromKernelIsBad
It's likely that you can do what you need but without opening files from within the kernel. If it's simply an academic project or for interest, then I suggest asking the kernelnewbies.org folks for help.
Jon.
