Full disk and 2.3.x kernels.

This problem appeared in early 2.3.x kernels. I believe I first saw it
in 2.3.11.

Scenerio: Let your disk fill very close to full. Erase a few hundred
megabytes of data so you can work on other things. Disk stays "full."
Your apps give you many many errors of such.

in 2.3.x<26 (26 may have been included in this), it never recovers. It
takes a reboot to get your disk space back.

In 2.3.x>28 (may include 26, I cant remember), two or three fails and
then bam, you have your space back.

Sync doesn't fix this. It seems to take failed writes.

I am not sure how to get more detailed than this or how to create a test
for you all save the conditions I observed. I am using an up to date (I
believe) RedHat 6.1 base.
