    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
    12

    # dd if=/proc/partitions bs=128k|wc -l
    0+1 records in
    0+1 records out
    32


    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()?
