From: Darrick J. Wong <darrick.wong@xxxxxxxxxx> Replace this homegrown inode pointer verification function with the libxfs checking helper. This one is a little tricky because this function (unlike all of its verify_* siblings) returned 1 for bad and 0 for good, so we must invert the checking logic. Signed-off-by: Darrick J.
