[LTP] [linux-next:master] [block/bdev] 47dd675323: ltp.ioctl_loop06.fail

[Li Wang]

Hi,

The ioctl_loop06 test expects PAGE_SIZE to be the upper limit, but the
kernel
now allows up to 64K (SZ_64K). If PAGE_SIZE < 64K (e.g., 4K on x86),
the test wrongly assumes anything above PAGE_SIZE should be rejected,
but the kernel now allows up to 64K.

I guess we probably need to adjust testcase to dynamically define an
EXPECTED_MAX_BLOCK_SIZE according to kernel versions.
I will send out a patch to LTP ML.
