Question ext4-dio-unwrit process count info

Hi All,

Hardware: IBM x3550M3
CPU: Xeon 2 x E5630 @ 2.53GHz
HDD: 2x146GB SAS 10K

Kernel: x86_64
OS: CentOS Linux release 6.0 (Final)

df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg0-lv0   9.7G  2.9G  6.3G  32% /
tmpfs                 7.8G     0  7.8G   0% /dev/shm
                       15G  5.2G  8.6G  38% /backups
/dev/sda1             291M   58M  218M  21% /boot
/dev/mapper/vg0-home  9.7G  151M  9.0G   2% /home
/dev/mapper/vg0-tmp   7.7G  793M  6.6G  11% /tmp
/dev/mapper/vg0-apps  9.7G  888M  8.3G  10% /usr/apps
/dev/mapper/vg0-isa   9.7G  619M  8.6G   7% /usr/isa
                       15G  173M   14G   2% /var/log/jboss
tmpfs                 1.0G     0  1.0G   0% /usr/apps/ramdisk
Is it normal to have >= 128 processes of ext4-dio-unwrit?

IIRC, it's one ext4-dio-unwrit process per CPU per ext4 filesystem.

Ted may have updated that in later kernels (I haven't looked).
On this (i7) laptop I only see two - for two mounted f/s and 4 h/t processors (kernel is 3.2.9).
