[Yaffs-archive] Re: benchmark yaffs with Bonnie++

I think the problem is in YAFFS unlink & readdir implementation.
Please see the attached test program. It should list & remove all
files in working directory. Try create/touch some file in directory
and run this program. If current directory contain >192 files, the
second readdir will not list all files.

#include <stdio.h>
#include <sys/types.h>
#include <dirent.h>

int main (int argc, char *argv[])
{
    DIR *dir;
    struct dirent *dirent;

    dir = opendir (".");
    while ((dirent = readdir (dir)) != NULL) {
          if(dirent->d_name[0] == '.')
              continue;
        printf ("file %s exists\n", dirent->d_name);
    }
    closedir (dir);

    dir = opendir (".");
    while ((dirent = readdir (dir)) != NULL) {
          if(dirent->d_name[0] == '.')
              continue;
        printf ("remove %s\n", dirent->d_name);
        unlink (dirent->d_name);
    }
    closedir (dir);

    return 0;
}
