change in src/vfs/extfs/extfs.c

[Nicolas Rybkin]

I want this change in src/vfs/extfs/extfs.c:
add to extfs_fstat() lines between BEGIN and END
static int
extfs_fstat (void *data, struct stat *buf)
{

struct pseudofile *file = (struct pseudofile *) data;

BEGIN:

struct stat tmp_stat;

if (!stat(file->entry->inode->local_filename,&tmp_stat))

{

file->entry->inode->mtime = tmp_stat.st_mtime;
file->entry->inode->atime = tmp_stat.st_atime;

}

END

extfs_stat_move (buf, file->entry->inode);
return 0;

}
So extfs script can set atime and mtime in copyout, and they will be set in the properties of destination file.
Why do I need this: I need to use 3 bytes to store some data related to file, I decided to store them in st_atime. As I learned if atime is bigger than mtime, atime won't be changed until mtime is changed. So my script sets atime of a copied out file to 0x7Fxxxxxx.
