Hello everybody,
I believe that I found a problem regarding ramfs and directory modification
times.
Observe:
$ /tmp# mkdir newdir
$ /tmp# mount -t ramfs none newdir
$ /tmp# cd newdir/
$ /tmp/newdir# mkdir sub
$ /tmp/newdir# cd sub
$ /tmp/newdir/sub# ls -la --full-time
total 0
drwxr-xr-x 2 root root 0 2006-02-23 14:01:37.573655160 +0100 .
drwxr-xr-x 3 root root 0 2006-02-23 14:01:33.221316816 +0100 ..
$ /tmp/newdir/sub# touch a-new-file
$ /tmp/newdir/sub# ls -la --full-time
total 0
drwxr-xr-x 2 root root 0 2006-02-23 14:01:37.573655160 +0100 .
drwxr-xr-x 3 root root 0 2006-02-23 14:01:33.221316816 +0100 ..
-rw-r--r-- 1 root root 0 2006-02-23 14:01:48.019067216 +0100 a-new-file
On a tmpfs or other (disk-based) filesystems (ext3) it works correctly.
Is that a design wish, that ramfs is kept as simple as possible?
Nevertheless I believe that should be fixed, as everything that relies on the
directory mtime won't work on an ramfs.
This is 2.6.26-rc4, btw, on x86.
Please CC me as I'm not subscribed (although I surely will have a look in the
archives, too).
Regards,
Phil
