Don't overdo it ;-).

While it may technically be true that this one instance is every
instance of (1<<27) there is in lustre_compat.h, I must say I expected
a bigger patch when I saw "replace all instances".

Isn't this used in lustre's userspace code? If so, you can't use the
BIT() macro there :(
Please check before you redo this.

The "lustre_compat.h" header was previously used for compatibility between different kernel
versions, which is why it is now basically empty. It isn't used for userspace interfaces
as other "compat" headers are in the kernel.
