Description of problem:
After upgrade the kernel to kernel-smp-2.4.18-18.7.x.athlon.rpm in a RH 7.2, 
and  kernel-smp-2.4.18-17.7.x.athlon.rpm in a RH 7.3. The ramfs didn't work 
well. If I deleted the files in ramfs mount point, the mount have the same used 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. mount -t /dev/ram /mnt/ramdisk -o maxsize=28000
2. cp /tmp/* /mnt/ramdisk
3. df
4. "/dev/ram      28000      4184     23816  15% /mnt/ramdisk"
5. rm -rf /mnt/ramdisk/*
6. df 
7. "/dev/ram      28000      4184     23816  15% /mnt/ramdisk"

Actual Results:  After I deleted the files in a ramfs mount point, the used 
size didn't decrease. Intead, the used size increase to empty the left space.

Expected Results:  I expexted the ramfs decrease the used size after I deleted 
some files.

Additional info:


Athlon (dual) with Red Hat 7.2 instalation: updgrade from kernel-2.4.9-
34.athlon.rpm to kernel-smp-2.4.18-18.7.x.athlon.rpm. The ramfs worked fine 
with Kernel 2.4.9-34

Athlon with Red Hat 7.3 instalation: upgrade from kernel-2.4.18-10.athlon.rpm 
to kernel-2.4.18-17.7.x.athlon.rpm. I didn't test the ramfs in Kernel 2.4.18-10 
enviroment, only in 2.4.18-17.7.x
