From: Darrick J. Wong <darrick.wong@xxxxxxxxxx> The -c parameter displays the cow fork information for a file if the kernel was built with CONFIG_XFS_DEBUG=y. Since xfs_bmap doesn't support it and it doesn't work generally, remove it from the manpages. However, xfstests relies on the -c command to be documented in the help screen so leave it there with a warning about its use. Signed-off-by: Darrick J.
