Description of problem:
Would it be possible to get the scsi tape driver (st.c) in the redhat 
enterprise kernel updated to the kernel-2.4.25 version?

This newer driver fixes an issue with tape drives using variable 
block size (which is darn near all current tape hardware). The 
version string for the newer driver is "20040102".

The only file that was changed is drivers/scsi/st.c (in the kernel 
tree). The new version was integrated in the 2.4.25 'reference' 

The changelog info for this is:

Move checking the status of previous write before possible buffer 
extension. Prevents possible data corruption in variable block mode 
if the buffer is being extended more than once.

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

How reproducible:
Didn't try

The new version of the st.c driver has just been committed to the
RHEL3 U3 patch pool this evening (in kernel version 2.4.21-15.12.EL).
