[LTP] [PATCH] mkswap: make the test device size is aligned to pagesize

[Li Wang <liwang@redhat.com>]

We get failures like below because of 'DEVICE_SIZE-10000' makes the
loop device size is not aligned to system PAGE_SIZE any more.

-----
mkswap01 1 TINFO : Found free device '/dev/loop1'
mkswap01 1 TPASS : 'mkswap   /dev/loop1 ' passed.
mkswap01 2 TFAIL : 'mkswap -f  /dev/loop1 92400' failed, not expected.
mkswap01 3 TINFO : Can not do swapon on /dev/loop1.
mkswap01 3 TINFO : Device size specified by 'mkswap' greater than real size.
mkswap01 3 TINFO : Swapon failed expectedly.
mkswap01 3 TPASS : 'mkswap -f  /dev/loop1 112400' passed.
