Bug#654206: linux-image-3.0.0-2-amd64: max_batch_time doesn't seem to work
 
Package: linux-2.6
Version: 3.0.0-6
Severity: normal

According to mount(*) the max_batch_time parameter for mounting an ext4
filesystem has a default value of 15000. When I try using it with values
of 10000 and 20000 it appears to not work:

# mount -o loop,max_batch_time=10000 test /mnt/tmp
# grep tmp /proc/mounts
/dev/loop0 /mnt/tmp ext4 rw,relatime,user_xattr,max_batch_time=0,barrier=1, data=ordered 0 0

The above example is for an attempt to use a max_batch_time of 10000, I get
the same result (max_batch_time=0 reported) when I mount with the value
20000.

I don't know whether the filesystem is actually mounted with the parameter I
requested, it could be mis-reported or it could be that the mount process isn't
doing what I desire.

I have repeated this bug with kernel 3.1.0-1-amd64 with the complete Unstable
user-space. I have also repeated it with kernel 2.6.32-5-686 on a stock
Squeeze installation with the latest updates applied.

[...]

It's misreported:

if (sbi->s_max_batch_time != EXT4_DEF_MAX_BATCH_TIME) {
seq_printf(seq, ",max_batch_time=%u",
(unsigned) sbi->s_min_batch_time);
}

However, the fact that you see it in the options at all shows that it
has been changed from the default.
