[Ocfs2-tools-devel] [PATCH 1/2] mkfs.ocfs2: Initialize fake superblock with poison

[Sunil Mushran]

fill_fake_fs() creates a fake ocfs2_filesys* so as to allow us to call
select libocfs2 functions.

This patch initializes the fake superblock buffer with 0xC0 instead of 0x00
so that we get errors if we inadvertently call a libocfs2 function that we
were not supposed to.
