Subject2.4.20-pre11 /proc/partitions read
	Hello, world!\n

while trying to figure out why my "vgchange -a y" sometimes works
and sometimes does not, I've come to the following problem:

# dd if=/proc/partitions bs=512|wc -l
1+1 records in
1+1 records out

# dd if=/proc/partitions bs=128k|wc -l
0+1 records in
0+1 records out

I.e. if you read the /proc/partitions in single read() call,
it gets read OK. However, if you read() with smaller-sized blocks,
you get the truncated contents.

Are applications expected to read the whole /proc file
in one read()?
